TL;DR: Eight years ago, we launched Timescale to bring time-series to PostgreSQL. Our mission was simple: help developers building time-series applications. Since then, we have built a thriving business: 2,000 customers, mid 8-digit ARR (>100% growth year over year), $180 million raised from top investors. We serve companies who are building real-time analytical products and large-scale AI workloads like: Mistral, HuggingFace, Nvidia, Toyota, Tesla, NASA, JP Morgan Chase, Schneider Electric, Palo Alto Networks, and Caterpillar. These are companies building developer tools, industrial dashboards, crypto exchanges, AI-native games, financial RAG applications, and more. We’ve quietly evolved from a time-series database into the modern PostgreSQL for today’s and tomorrow’s computing, built f…  ( 6 min )

Hi — I’m Timothy. This post is a reflection — not about regret, but about understanding how we end up making the choices we do… and how sometimes, we grow out of them. The First Shift: Into BSE But I never thought of software as a career. At the time, the word “developer” to me meant IT support, someone fixing printers or helping you reset passwords. I couldn’t yet imagine that people like Elon Musk or Bill Gates also started with code — and used it to build entire systems and companies. When it came time to choose a major, I followed the advice around me. People said BSE had good career prospects, it was practical, and in demand. So I transferred universities and committed to the path. I didn’t know much about HVAC systems, fire services, or green buildings — but I was accepted, and I be…  ( 5 min )

This week’s episode: how I accidentally DDoS’d our own backend... from inside the backend. We had a microservice A that relied on service B for fetching customer data. One fine morning, I decided to make our request to service B more “resilient.” Added a retry block using the new HTTP client wrapper. Something like: for _ in range(3): try: response = call_service_b() break except: time.sleep(1) Looks harmless, right? Well… Here’s what I missed: Service B was already failing due to a separate deployment issue. The retry logic was not exponential, and ran for every request. Service A was deployed to all nodes, each now retrying every request 3 times. Multiply that by: 5K requests per second 3 retries 6 instances 🎉 Congratulations! You just self-DDoS’d your own service. Both A and B went down in under 90 seconds. Retries aren’t magic. Add exponential backoff. Add limits. Add circuit breakers. And most importantly add rate limits, yes even for internal requests. Log retries explicitly. So you don’t have to grep through 500MB of logs later. Monitor retry rates—because a spike might be hiding a deeper issue. ✅ The Fix We rolled back, patched in exponential backoff + error rate logging. Trying to make things more reliable can backfire spectacularly if you forget to put guardrails. Don’t just retry. Retry wisely.  ( 3 min )

We explored about A2A and MCP in the previous blogs and how can we use them to work together. Now let's shift focus from protocols to building actual multi-agent systems. There are several SDKs and frameworks available that the community uses today like CrewAI, LangChain, OpenAI Agent SDK, and Google Agent Development Kit (ADK). While exploring options, I couldn’t find a clear comparison of these frameworks so I made one. Each SDK brings something different to the table, from simplicity and flexibility to enterprise-grade scalability. In this blog, I’ll compare these four based on real parameters, using a simple and consistent example to highlight their strengths and trade-offs. The goal here is to help developers (like you and me) pick the right multi-agent framework. We'll look at: Ease …  ( 13 min )

As a third-year computer science student, I have repeatedly experienced how architecture design determines code maintainability and development efficiency. Every time a project grows or requirements change, poor architecture becomes a nightmare. Only after using this Rust web framework did I truly understand that "architecture is productivity." Today, from the perspective of a ten-year editor and developer, I want to share my thoughts on modern web architecture, modularity, type safety, and error handling, based on real project experience. In traditional Node.js or Python web frameworks, project structure often becomes chaotic as business grows. In contrast, this framework naturally supports layered architecture, making code organization clear and maintenance easy. // lib.rs - Main applica…  ( 4 min )

As a DevSecOps engineer, my daily grind usually involves CI/CD pipelines, security audits, and infrastructure as code. So, when the "Build Games with Amazon Q CLI" campaign popped up, it was a refreshing detour from the usual. The idea of conjuring a game with just conversational prompts, powered by Amazon Q CLI's Claude 4 large language model, was too intriguing to pass up. This isn't the usual realm of an "enthusiast" for me, but more of an exploration into how AI can augment a developer's toolkit, even outside their primary domain. My concept for the game was heavily inspired by the classic "Space Trilogy" narratives (you know the ones 😉), where the good guys wield blue "light swords" and the antagonists opt for menacing red ones. I wanted to capture that classic duel vibe, with player…  ( 6 min )

Let’s be honest, PostgreSQL is great, but documenting its schema isn’t. You open the database, and all you get is a list of tables. If you’re lucky, maybe a few constraints. But if you actually want to understand how the database works, or explain it to someone else... good luck. I’ve seen this problem a lot, especially in teams. Everyone assumes someone else is handling the documentation. Then months later, you’re stuck trying to figure out what client_log_v2 was meant to do. That’s why I started using DbSchema. It gives you diagrams, interactive docs, and actual context, without having to dig through SQL files or guess what each table is doing. Here’s how I document PostgreSQL databases now. It saves me time and makes it way easier to collaborate with the team. DbSchema connects to your …  ( 5 min )

Multi AI-Agent systems represent a significant advancement in software development, characterized by two fundamental aspects: Collaborative Intelligence: Multiple AI agents working together to achieve shared objectives, each contributing their specialized capabilities. Dynamic Decision Making: Systems that employ AI-driven tool calling to determine execution paths based on real-time context, rather than following predetermined logic flows. The dynamic nature of these systems presents a unique challenge: understanding the flow of logic becomes increasingly complex as the system scales.

型安全な開発 JavaScript (JS) は非常に柔軟な言語ですが、その柔軟性ゆえに、特に大規模なアプリ開発では予期せぬエラーやバグ発生のリスクが高くなります。そこで登場するのが、TypeScript (TS、タイプスクリプト) です。 TypeScriptは JavaScript に「型」の概念を加えたスーパーセットです。 TypeScript を使うと、記述したコードの型が正しいかどうかを、アプリ実行前にチェックしてくれます。これにより、以下のようなメリットがあります。 メリット 説明 開発効率の向上 型定義により実装者の意図が明確になる。コード補完が強化される。 バグの早期発見 アプリ実行前に、型の不一致としてエラーを検出でき、修正コストを削減できる。 コードの可読性・メンテナンス性 型情報により、コードの意図が明確になり、共同開発や長期運用の助けになる。 開発効率の向上: コードを書いている最中に、変数や関数の型が明確になるため、どのようなデータを受け取るか、何を返すかを迷うことが少なくなります。 エディターの自動補完が強化され、タイプミスや関数名の間違いなどが減ります。 バグの早期発見: コンパイル時に型の不一致などのエラーを検出できます。開発の早い段階でバグを見つけることができ、実行時エラーで検出する場合と比べて、修正コストを削減できます。 コードの可読性とメンテナンス性の向上: コードに型が明記されているため、他の開発者 (または未来の自分) がコードを読む際に、データ構造や関数の意図を理解しやすくなります。 大規模なプロジェクトや複数人でのチーム開発において、コードの品質を保ちやすくなります。 // JavaScript function greet(name) { // name が文字列であることを期待している // しかし **数値やオブジェクトが渡されてもエラーにならない** // その結果、予期せぬ挙動になる可能性がある return 'Hello, ' + name } console.log(greet('Alice')) // "Hello, Alice" console.log(greet(123)) // "Hello, 123" (もっと複雑なコードでは意図しない結果になる可能性) // TypeScript // name は必ず文字列、戻り値も文字列であることを明示 function greet(name: string): string { return 'Hello, ' + name } console.log(greet('Alice')) // "Hello, Alice" // console.log(greet(123)) // エラーまたは警告: Argument of type 'number' is not assignable to parameter of type 'string'. // 意図と異なる型のデータを渡そうとするとエラーや警告が出るため、 // 関数作成者と使用者それぞれで安全なコード記述ができる このように、 TypeScript を導入することで、より安全で堅牢なコードを書くことができるようになります。  ( 3 min )

Hi Devs 👋 Last week, I launched MintYourMood, a React-based PWA that lets users turn their mood into a custom-designed NFT — and mint it on the Polygon blockchain. Built with React + Thirdweb, this project was a mix of frontend fun and Web3 logic. Here’s how (and why) I built it. 🎯 The Idea What if you could turn your mood of the moment into an NFT — a little capsule of emotion minted forever? And that’s how MintYourMood was born. 🧱 The Tech Stack Frontend: React + TailwindCSS PWA: Fully installable (Add to Home Screen) Web3: Thirdweb SDK for wallet connections, NFT minting, storage Storage: IPFS via Thirdweb's upload Design to NFT: html-to-image + IPFS Chain: Polygon (MATIC) ⚙️ How It Works User inputs: emoji, name, quote, selfie Visual generation: The app creates a mood card using html-to-image IPFS upload: Both image + metadata get uploaded Minting: Via mintWithMetadata() on a custom ERC-721 contract All done inside the browser. No backend required. 🧪 Dev Challenges React hydration and conditional Web3 hooks — caused some tricky race conditions. IP geolocation block — added basic client-side check to restrict access in high-risk countries. Cookie storage duration logic and syncing across tabs (localStorage + storage events). 🧠 What I Learned Thirdweb is fantastic for Web3 projects — wallet connect, contract calls, IPFS — all in one. User privacy handling is essential in crypto apps — even for something as light as emoji NFTs. Dev-first NFT tools make launching onchain experiences smoother than ever. 🖼️ Try It Out 🔗 https://mintyourmood.com Give it a spin and mint your current vibe. Got feedback, ideas, or bugs?

For decades, SQL has been the backbone of data querying. But as machine learning and natural language interfaces become more mainstream, a growing number of teams are asking: Can we make our accounting systems smarter than traditional SQL allows? The answer lies in vectorizing structured accounting data. In this article, we’ll explore why product managers and engineering leads should consider vectorization for structured accounting data — especially in the age of AI. You’ll learn how it works, how to implement it, and how it opens doors that SQL simply can’t. Structured accounting data (invoices, journal entries, bills, etc.) maps beautifully to relational databases. But traditional SQL querying has limitations: Exact matching bias: SQL excels at filtering exact matches (e.g., WHERE custom…  ( 6 min )

Stock price data is everywhere online, meaning opening, closing, high, low, volume, and a bunch of indicators based on them. It’s free and easy to get. On the other hand, other types of data that could be useful for forecasting, like financial statements or market sentiment, are often harder to find, and can be really (sometimes really) expensive. Because of that, a lot of people have tried to predict the stock market using just price data, especially the closing price. You can find plenty of articles showing models that seem to do a good job, with predicted prices that look very close to the actual ones. But in many cases, these articles don’t include proper evaluation, even basic metrics like MAE or MSE are often missing. So that got me thinking: Can we actually forecast stock prices usi…  ( 14 min )

1. Introduction to Spring Framework The Spring Framework is a powerful platform for developing Java applications. It started in 2002 and helps developers build secure, efficient, and maintainable software. Think of Spring as a toolkit that organizes and wires up all the parts of a Java application so you don’t have to do it manually. Inversion of Control (IoC) and Dependency Injection (DI)—fancy terms that simply mean Spring creates and manages the objects your app needs and connects them together. Traditional Java EE (Before Spring): Spring’s Solution: Less code: Write only what’s necessary. Better testability: Easily test parts of your app without starting the whole app. Simpler wiring: Let Spring create and connect the objects. Legacy Java EE Architecture: • Tightly coupled component…  ( 5 min )

Let’s start with a question that’s been bugging AI researchers for years. Why do tiny, almost invisible changes in an image completely throw off deep learning models? You show a photo of a panda. The model confidently says “panda.” Then you tweak a few pixels — changes you probably wouldn’t even notice — and suddenly it screams “gibbon.” That’s not just weird. It’s dangerous in real-world systems like self-driving cars or medical diagnostics. This kind of failure is what we call an adversarial attack. And the usual defenses? They mostly involve tweaking the inputs or training models to resist certain attacks. But these fixes are limited. They patch symptoms without solving the root cause. So we asked a deeper question: What if robustness isn’t about fighting off attacks at the input level?…  ( 5 min )

It's a common programming concept, not specific to Java, but widely applied in various contexts within Java development. Boolean Flags: The most common type of flag is a boolean variable. It holds a true or false value, indicating whether a specific condition has been met or a particular state exists.

We'll focus heavily on a core principle of software development: DRY (Don't Repeat Yourself). Writing the same code over and over is slow, error-prone, and a nightmare to maintain. We'll tackle this by mastering TypeScript's fundamental logic: Functions, Loops, and Conditionals. By the end, you'll be able to write automation that isn't just a series of steps, but an intelligent, robust system. This article assumes you are comfortable with the topics from our previous discussion: Basic Typ…  ( 8 min )

A no-fluff breakdown of what actually works for modern software teams. If you've ever juggled GitHub, Jira, Notion, Slack, and Zoom while working across time zones, you know the real pain of remote development isn't writing code—it's managing all the other stuff. Communication gaps, tool fatigue, and misaligned workflows can slow your team down more than bad code. So, in 2025, what do dev-first teams actually use to stay productive, async, and collaborative? This post breaks down the best project management tools developers are using in the wild—based on hands-on usage, community buzz, and features that make sense for actual developer workflows.

TL;DR: We’re no longer limited to using generic productivity tools. With the rise of AI-assisted coding and platforms like v0, Bolt, Cursor, and Windsurf, it’s now possible to build simple, custom tools (microtools) that fit the way you think and work. This shift is not just about convenience; it marks a deeper change in how we relate to software. We’re moving from using tools to making them. These tools aren’t always clean or scalable, but they let you solve your own problems without waiting for someone else to build the solution. That said, real programming knowledge still matters, especially when you're building something meant to last. AI gives us speed and leverage, but it’s skilled developers who make things work. Organizing your ideas, tasks, or notes often means using a general-pur…  ( 9 min )

Bridging Design and Code with Image-to-Compose UI The Declarative Advantage of Jetpack Compose Okay, so, Jetpack Compose is kind of a big deal. Instead of messing around with XML, you describe what you want your UI to look like using code. This declarative approach makes things way easier to understand and maintain. Think of it like telling a story instead of drawing a blueprint. You say what should happen, and Compose figures out how to make it happen. It's a different way of thinking, but once you get the hang of it, you'll wonder why you ever did it the old way. Plus, it plays super nice with Kotlin, which is another win. It's all about making Android development less of a headache. You can build native Android UI with less code. From Visual Concepts to Functional Components So, you've …  ( 6 min )

Originally published by Cyril Scetbon on June 16, 2025 In my previous post, I explored why SurrealDB is unlike any other database: it blends document, graph, relational, and vector models into one engine - and it's written in Rust. That flexibility makes it a perfect match for Rig.rs, a toolkit for building LLM-native agents in Rust. Today, I’m going to show exactly how the two fit together by building a basic knowledge agent - one that embeds word definitions and answers questions using that content without having to manage the lookup yourself. Let me rig this thing. 🔧 I’m building a context-aware support agent that: Ingests internal documents Embeds them into vector space Stores everything in SurrealDB Finds relevant documents using cosine similarity Passes those to an LLM to generate a…  ( 5 min )

Imagine this. You’ve just added your favorite shoes to an online cart. You tap “Buy Now.” The screen flickers. Within two seconds, it confirms: “Payment Successful.” Simple, right? But what if I told you that behind that one tap is a fast-paced digital relay race—one that determines whether you get your shoes, or a payment failed notification? Welcome to the hidden world of payment gateways. At its core, a payment gateway is the tech bridge between your business and the banks. It encrypts data, validates the card, talks to processors, and returns an instant “approved” or “declined” result. It does all this in under 3 seconds. But that’s just the surface.

A Segment Tree is a data structure that stores information about array intervals as a tree. This allows answering range queries over an array efficiently, while still being flexible enough to allow quick modification of the array. This includes finding the sum of consecutive array elements a[l... r], or finding the minimum element in a such a range in O(log n) time. Between answering such queries, the Segment Tree allows modifying the array by replacing one element, or even changing the elements of a whole subsegment (e.g. assigning all elements a[l...r] to any value, or adding a value to all element in the subsegment). You are given an array A[], and you want to perform: Range queries: e.g., find the sum, minimum, or maximum in a subrange A[l...r]. Point updates: change a value at a speci…  ( 5 min )

On June 16, 2025, WhiteBIT Coin (WBT) reached a new all-time high of $52.27, following a series of steady price gains throughout the year.

Alright, let me be honest right out the gate: I always thought Vim was just some arcane flex tool for terminal nerds. You know — the kind ThePrimeagen uses at lightspeed while yelling "LET'S GO!" on stream. It looked cool. It sounded fast. But it also looked like a keyboard-induced migraine. Still… I was curious. So I decided to see what the hype was all about. Day 1 with Vim felt like: "How do I quit?" "Why can't I type?" "Oh cool, I deleted the entire line again." It was confusing. It was rigid. It felt like Vim was a gatekeeper, not a helper. I legit thought, "This is just a thing YouTubers use to feel cool." And maybe it is — a little. But I kept going. Somewhere around day 3 or 4, I stopped trying to fight Vim. I started noticing that: The modal editing wasn't stupid — it was intentio…  ( 4 min )

The threats to cybersecurity are occurring at an unprecedented rate, and therefore, security testing must ensure organisational protection. External network penetration testing plays a pivotal role in helping you discover the vulnerabilities that can be used by malicious individuals outside your network perimeter. ** ** ** Public-facing web applications and services ** Automated tools do provide broad coverage; however, complex vulnerabilities are likely to be identified using manual techniques. Both methods offer the most comprehensive evaluation possible. ** ** ** Automated domain scanning, subdomain enumeration, and service fingerprinting are all great reconnaissance techniques that will help uncover meaningful information that will assist us in our next steps in the testing process. ** You will need to consider the exploitation frameworks you select for assessment and develop a careful methodology or protocols for testing the possible vulnerabilities that you exploit. Record all your findings, including steps to reproduce those findings, and document the potential impacts on the organisation's business. ** ** Social engineering awareness training complements technical testing by addressing human vulnerabilities that technical tools cannot detect. Combining network testing with social engineering assessments provides a comprehensive security evaluation. ** ** ** ** ** ** ** Want to improve your external security posture?

Hey friends! 👋 It’s a new week and I’m back with another quick, easy tutorial. This time we’re talking about JavaScript objects. Objects used to confuse me a little. Now I just think of them as mini folders storing related info. Let's break it down. Object? An object in JavaScript is like a shopping cart 🛒. const cart = { 'item-name': 'Laptop', price: 2000, quantity: 1 }; Here: 'item-name' is the key and 'Laptop' is its value: this tells us what’s in the cart. price is the key and 2000 is the value: how much the item costs. quantity is the key and 1 is the value: how many you're buying. So instead of remembering each piece of info separately, you group it all inside one neat object: your cart 🛒. It makes data easy to organise, update and use You can use dot notation: console.…  ( 5 min )

For many students, learning algorithms starts in a classroom, surrounded by whiteboards filled with graphs, loops, and pseudocode. It's easy to assume these abstract concepts exist only for exams or coding interviews. But step outside the classroom, and it becomes clear that algorithms shape far more than academic success—they influence our daily routines, business decisions, and digital experiences in ways we rarely notice. Take your morning commute, for instance. When you open a map app to find the fastest route, it doesn’t just show streets. It runs complex algorithms—like Dijkstra’s or A*—to evaluate traffic, road closures, and travel time. The result? A path optimized for speed and efficiency, all computed in the background within seconds. Online shopping is another area where algorit…  ( 4 min )

Disclaimer: I built Myriade (and I love it ^^) Let’s be honest: writing SQL can feel like a chore — tedious and tricky. Myriade is an AI-powered tool designed to make database queries easy and intuitive. — no SQL needed. Start by hooking up your Postgres database to Myriade. Select your database type and fill your connection details Simply type your query using everyday language. For example: “What were the sales figures last quarter?” “Explain the decrease in user sign-ups yesterday.” You don’t even need to worry about field names or tables — Myriade figures that out for you. After you ask, Myriade transforms your plain-English question into SQL, fetches the data, and presents clear results as tables, graphs, or easy-to-understand insights. Using a database about Formula 1 Data security matters, so Myriade comes with built-in privacy: Read-Only Mode: No chance of accidentally editing or losing data. Sample Only: The AI only reads a sample of the results (like a human would) AI — Zero Data Retention: Nothing you query gets stored on the AI providers. Zero Knowledge Protection: Advanced features to hide your sensitive data from AI providers. Myriade isn’t just for basic queries. Here are some practical scenarios you can try: Diagnose a Problem: “Why did sales drop on March 10?” Find What’s Missing: “What key metrics aren’t in our monthly reports?” Shape Your Data: “Make a quick table showing each user’s last purchase.” Check Your Data Quality: “Spot any weird duplicates in billing data.” With Myriade, interacting with your database feels less like coding and more like chatting. myriade.ai.

This article explains why we should build our Angular apps with reactivity in mind and how immutability helps with it. Look at this example: @Component({ template: ` Name: {{user.name}} Age: {{user.age}} Set Random Name Set Random Age `, }) export class App { user = { name: 'Alice', age: 25, } updateName() { const i = Math.floor(Math.random() * names.length); this.user.name = names[i]; } updateAge() { this.user.age = Math.floor(Math.random() * 20 + 20); } } It works, but it only works because of magic. Dark magic. I wish it didn’t work :) What’s m…  ( 10 min )

To set up the CAN filter on an STM8 microcontroller (like STM8S or STM8AF series with CAN capability), you need to configure the CAN filter registers to determine which messages the MCU should accept or ignore. Here’s a structured overview of how to configure the CAN filter: 1. Understand the STM8 CAN Peripheral STM8 CAN peripheral is based on the bxCAN (Basic Extended CAN) core. The CAN filter allows mask-based or list-based filtering. You can filter on standard (11-bit) or extended (29-bit) IDs. 2. Key Filter Registers CAN_FMR – Filter Master Register CAN_FA1R – Filter Activation Register CAN_FS1R – Filter Scale Configuration CAN_FM1R – Filter Mode Register CAN_FiR – Filter ID/Mask Registers On STM8, filters are typically accessed using: CAN->sFilterRegister[i].FR1 (Filter bank register…  ( 4 min )

Hey devs 👨‍💻 I just read a post on CMC that really nailed something I’ve been noticing in my own work: broker models are no longer optional for Web3 infra — they’re the new default. A few years ago, exchanges were just backend pipes for liquidity. Today, they’re go-to-market tools, monetization channels, and sometimes the biggest user acquisition engine you’ll ever plug into. That’s a massive shift for those of us shipping wallets, terminals, or anything API-driven. The WhiteBIT case in the article stood out. Their broker model doesn’t just offer API keys and walk away. It gives: Up to 40% revenue share (that’s real money for bootstrapped teams), Custom terms for different product types (finally, someone who gets that a wallet ≠ a DEX ≠ a terminal), Co-marketing and even user tournaments (which can be more effective than paid ads, tbh), Plus: fast onboarding and solid support — which makes a huge difference when you’re on a tight dev cycle. What hit home most? The article also breaks down the Atani x Kraken use case. Worth reading — it shows how good UX, embedded trading, and real-time commission logic actually improve LTV and retention. Something I’ve seen in my own builds too. Anyway, just thought I’d share. If you're building infra and haven't thought about embedded exchange layers or broker monetization, now’s the time.

Forms are essential in nearly every web application — from login and registration to onboarding and settings. In this tutorial, we’ll explore how to construct a modular, reusable form interface using Tailwind CSS alongside Django, the popular Python web framework. Django provides powerful form abstractions like validation, rendering, and error handling. But the default rendering isn’t styled for modern UI. Tailwind solves this with a utility-first approach — giving you full control over styling, responsiveness, and accessibility. To make Django forms look great with Tailwind, you can: Override default widgets Inject custom CSS classes into form fields Use third-party packages like django-crispy-forms or django-widget-tweaks Here’s how to style a text input manually: from django import f…  ( 4 min )

As frontend performance expectations rise, developers are exploring how to bring systems-level speed to the browser. Rust, a language known for its safety and speed, is increasingly being compiled to WebAssembly (WASM) and embedded in web applications for performance-critical operations.

Rust is known for its blazing-fast performance without a garbage collector and at the heart of that magic lies ownership. For devs coming from languages like Python, JavaScript, or even C++, Rust’s ownership model might feel a little strict at first. But once you get the hang of it, it becomes your best ally in writing safe, concurrent code without worrying about memory leaks or race conditions. Let’s break it down with real-world analogies and simple concepts. In Rust, every value has a single owner—a variable that holds responsibility for it. When you assign that value to another variable, the ownership moves. The original variable is no longer valid. `let book = String::from("Rust Book"); let borrowed = book; // book is moved here // println!("{}", book); ❌ Error: book no longer owns t…  ( 4 min )

Hey dev.to community! In my very 1st post where, I have decided to learn django by building small projects. Here is an update on my progress: Did the initial project setup and created a Products app. Created a Product model with slug field which is generated automatically. With slugs SEO-friendly URLs can be created(will write more about this in future post). Created RESTful endpoints(GET, POST, PUT and DELETE). Create Product serializer. I am amazed by how using a few lines of code these APIs can be written utilising Django REST framework generic views. These generic views simplifies the creation of API endpoints for performing CRUD operations. For example, in this project I have created just two views which handles CRUD operations in few lines of code. ProductListCreateView: Uses generics.ListCreateAPIView to get list of all the products(via GET request) and create a new product(via POST request). ProductDetailView: Uses generics.RetrieveUpdateDestroyAPIView to get a single product(lookup based on slug field), PUT request to update a product, DELETE request to remove a product. Another good thing is, Browsable API provided in DRF. One can interact with APIs, test and debug it. Next, I will be working on Categories of the product, expand CRUD operation to categories and get into django admin interface. Also attached some screenshots of the APIs and code. Complete code available here.  ( 3 min )

Introduction Yes, GraphQL can call REST APIs. In fact, this is a common way to use GraphQL in real projects. It lets you use your existing REST services while giving frontend apps the flexibility of GraphQL. In this article, you’ll learn how to call REST from GraphQL using a very simple and practical method. Many apps already have REST APIs. Instead of replacing them completely, you can wrap those APIs with GraphQL. This lets frontend developers ask only for the data they need, without changing your backend. You get the best of both worlds: Use existing REST endpoints Expose a cleaner GraphQL API to clients We’ll create a GraphQL server using Node.js, and we’ll call a public REST API: https://jsonplaceholder.typicode.com/users/:id This is a fake REST API that returns fake user data.…  ( 4 min )

Now let's dive into how this is achieved using classes in C++. class Student { private: int scores[5]; // Each student has 5 scores public: void input(); int calculateTotalScore(); }; We define a class Student to encapsulate the scores and operations. scores[5] is a fixed-size array holding 5 test scores. input() allows entering the scores. calculateTotalScore() adds up the scores. void Student::inpu…  ( 5 min )

Today, I'm going to share about lazy loading in the Cangjie development language. First, let me explain to the beginner friends what lazy loading is. Lazy loading is called LazyForEach in the code. Judging from the name, you can surely guess that its function is similar to that of ForEach. Unlike ForEach's one-time loading of all data, lazy loading loads data on demand based on the available area of the screen. Moreover, when the content slides out of the screen range, lazy loading automatically destroys this content. Therefore, lazy loading significantly optimizes the performance of the program and greatly improves the user experience. This point has already been compared by Youlan Jun in the ArkTs language. When there is a large amount of data, it is strongly recommended that everyone us…  ( 4 min )

Disclaimer: This content is for educational purposes only. I still remember the launch day of our first progressive web app (PWA). We had tested everything — or so we thought. But when users started pouring in, so did the bugs. Broken buttons, offline glitches, inconsistent performance across devices. It was a nightmare. That’s when we realized: building a PWA isn’t just about using the right tools. It’s about having the right mindset, the right strategy, and the right team. Fast forward to 2025, and the landscape has matured. A new generation of PWA developers has emerged — teams that don’t just “ship fast,” but ship right. They’ve solved the bugs. They’ve squashed the delays. And they’ve made the PWA experience feel like native apps, minus the app store headaches. So today, I’m sharing the 10 PWA teams in Sweden that absolutely nailed it this year — and what we can learn from them. 1. Bluell AB (Stockholm) 2. Netlight Consulting 3. Creuna (Now part of Knowit) 4. Tretton37 5. Monterosa 6. B3 Consulting Group 7. Iteam 8. Cybercom (now part of Knowit) 9. Valtech Sweden 10. Qvik So… What Sets These Teams Apart? 1. They Design for Offline First 2. They Test in the Wild 3. They Use the Right Stack 4. They Automate Everything 5. They Talk to Their Users The Real Lesson? It’s Not Just About Tech You can use React and still have janky transitions. You can follow “best practices” and still miss the mark. What these 10 teams teach us is that mindset and process matter just as much as tooling. They listen. They iterate. They care. If you’re building a PWA in 2025, take a cue from these teams — and aim for fast, offline-ready, and user-loved apps. Or even better, find the right team and let them take the lead. 😉  ( 5 min )

Enumerated fields in data tables have a limited number of predefined values. Filtering conditions on the enumerated field f are often expressed as f =v1 or f =v2 or ...; f !=v1 and f !=v2 and ...; in; or not in. The database has to compare f with n values. When the data table is large, the number of comparisons will be very high, leading to poor performance, and the performance worsens as n increases. If comparisons can be avoided during filtering, performance will naturally improve significantly. esProc’s aligned sequence mechanism can achieve this effect. The following example uses the orders table to demonstrate how to use aligned sequences, and also compares the performance of esProc SPL and MySQL database in calculating conditional filtering on enumerated fields.

Hey Devs! 👋 I recently started learning front-end development under devsync.in, and one of the first things that clicked for me was how powerful CSS can be. HTML gives you the structure, but CSS? That’s where the magic happens — colors, spacing, layouts, and even animations. 🚀 What is CSS? CSS stands for Cascading Style Sheets, and its main job is to style HTML elements. Think of HTML as the skeleton of your webpage, and CSS as the clothes it wears. Hello, World! Hello h1 { color: green; } I personally prefer external stylesheets — it's how I was taught at devsync.in, and it really helps in keeping things clean and scalable. 📐 Understanding the CSS Box Model One of the most important concepts I've learned at devsync.in is the box model. Each HTML element is a box made of: Content Padding Border Margin Think of it like layers from the inside out. 💡 Pro tip: Add this to your CSS reset: * { box-sizing: border-box; } This makes layout calculations much easier! 🧠 Final Thoughts Learning CSS with the support of devsync.in has been a game-changer for me. It’s not about memorizing every property — it’s about building a solid foundation and experimenting as you go. Once you understand the basics, it becomes way easier (and more fun!) to create beautiful web pages. If you're also learning or struggling with CSS, I’d love to connect and share tips. Drop your thoughts in the comments — let’s grow together! 🌱  ( 4 min )

If you’ve worked in the Microsoft development ecosystem, you’ve likely encountered both .NET and ASP.NET—but do you really know the difference between the two? Knowing when to use which can save your team time, money, and a lot of technical headaches. Let’s break it down in simple terms. 🔍 What is .NET? You can use .NET to build all kinds of applications: Desktop (with WPF, Windows Forms) Web Mobile (via .NET MAUI or Xamarin) Cloud-native apps Console apps APIs Microservices So in short, .NET is the entire framework (or ecosystem) that powers modern applications. 🌐 What is ASP.NET? ASP.NET provides: Server-side web development tools Razor pages & Blazor for UI MVC architecture RESTful API development support Authentication and identity handling There’s also ASP.NET Core, which is the modern, cross-platform version—lighter, faster, and designed for today’s cloud-based apps. ⚔️ ASP.NET vs .NET: What’s the Real Difference? 💡 When Should You Use Each? If you're building a web application or REST API → Go with ASP.NET (preferably ASP.NET Core). If you’re developing a desktop app, mobile app, or background service → Use .NET (and the right toolkit like WPF, MAUI, etc.).

Introduction: In this post, I’ll explore how Microsoft's Copilot strategy might be the root cause, and why this issue goes beyond just a performance glitch. We’re talking about a larger systemic problem that could have far-reaching implications. Copilot's Impact on Traffic: Microsoft’s decision to embed Copilot across all of its products—from Windows to Office tools—has caused a massive increase in the backend traffic directed to OpenAI’s servers. The issue isn’t just that Copilot is working; it’s that its presence in nearly every Microsoft product is consuming far more resources than anticipated. When you open Notepad or start a simple task in Excel, Copilot might be quietly running in the background, sending requests and consuming resources without you even realizing it. This unseen traf…  ( 5 min )

Leverage: The Promise of Big Gains with Little Capital Leverage trading sounds like a fast lane to profit. Put in a small amount, borrow the rest, and ride a 10× position to a fat payday. Crypto platforms love to flaunt this feature—just a few clicks and you’re controlling thousands of dollars' worth of Bitcoin or ETH. At its core, leverage trading means borrowing money to increase your position size. You commit a portion of your capital (called “margin”) and borrow the rest from the exchange to make a larger trade than your funds would normally allow. To open a leveraged position, you need to provide an initial margin—your skin in the game. Exchanges also enforce a maintenance margin, the minimum equity you must maintain to keep your trade open. You use $1,000 as margin to open a $10,00…  ( 6 min )

Ever wonder why some developers ship features while others struggle with endless meetings and Slack pings? The secret isn't working longer—it's working deeper. Last month, I show interview of 15 senior engineers from companies like Netflix, Stripe, and Shopify. One pattern emerged across every conversation: they all protect sacred blocks of uninterrupted time. Not 25-minute Pomodoros. Not "quick focus sessions." Two full hours of pure, distraction-free development. The results? One Staff Engineer told me he ships more code in his 2-hour block than most devs do in an entire day. Another said it's the difference between being a "ticket-taker" and an actual problem solver. Here's how they do it—and how you can replicate their system starting tomorrow.

SafeLine is an open-source Web Application Firewall (WAF) that’s easy to deploy, highly effective, and trusted by developers to defend web services against modern attacks. In version 7.1, SafeLine introduced a powerful new feature: Custom NGINX configuration for site-specific location blocks. This enhancement gives users fine-grained control over NGINX behavior per site. If you're wondering how to use it, you're in the right place. location Block in NGINX? In NGINX, location blocks are used to match incoming request URIs and apply specific rules — such as routing, proxying, security, or caching. For example: location /api/users { proxy_pass http://backend_service; } This tells NGINX how to handle requests to /api/users — in this case, by forwarding them to a backend. location Block…  ( 4 min )

As a computer science junior, my work on a web service project introduced me to the Hyperlane framework. This high-performance Rust HTTP framework fundamentally altered my view of web development. Here's a genuine account of my experience learning and using Hyperlane. ctx Abstraction When I first began using Hyperlane, I was immediately impressed by its clean Context (ctx) abstraction. In other frameworks, I was accustomed to writing more verbose calls, such as: let method = ctx.get_request().await.get_method(); With Hyperlane, this simplifies to a single line: let method = ctx.get_request_method().await; This design significantly boosts code readability, especially when handling complex business logic, by removing the need for deeply nested method calls. Implementing RESTful APIs with…  ( 5 min )

Introduction If you've ever browsed AWS EC2 instance types and found yourself staring blankly at names like m5.large, c6g.xlarge, or r7a.2xlarge, you're not alone. At first glance, these names can feel cryptic—like trying to decode a secret code. But here's the good news: there's a method to the madness. Each part of an instance type name tells you something important about the underlying hardware, performance characteristics, and intended use case. In this blog post, we'll break down the structure of AWS instance type names and show you how to read them like a pro. Once you understand how to interpret each component, you'll be able to confidently choose the right instance for your workload—and maybe even impress your colleagues with your cloud fluency. Every AWS EC2 instance type name i…  ( 6 min )

Hello, Today, I took a lecture from freecodecamp.com's Full Stack JavaScript course and learned about memory management. When a variable is created, it retains its memory address. function createLargeArray() { let printArrayLength = createLargeArray(); This snippet demonstrates that although createLargeArray() can't be trashed, it is still closed, and the return access means that more memory is used than expected.  ( 3 min )

LeetCode 2966 | Medium | Greedy + Sorting You are given: An integer array nums of size n (where n is a multiple of 3) A positive integer k Your task is to divide nums into n / 3 arrays of size 3, such that in each group, the difference between the maximum and minimum elements is at most k. Return: A valid 2D array of groups if possible. Otherwise, return an empty array []. Multiple valid answers are allowed. We need to split the array into triplets where max difference ≤ k. The optimal approach is: Sort the array: close values come together. Greedily pick every 3 consecutive elements. If the difference between the 1st and 3rd in any triplet exceeds k, it's invalid. This ensures we get the smallest difference across every triplet and maximizes the chance of valid grouping. class Solution…  ( 5 min )

The Serverless Paradox: How Hybrid Architectures and AI/ML are Taming Cold Starts and Vendor Lock-in Serverless computing has emerged as a transformative paradigm in modern application development, promising unparalleled agility, scalability, and cost efficiency. By abstracting away the complexities of infrastructure management, serverless allows developers to focus purely on writing code, with cloud providers dynamically managing resource allocation and scaling. However, this revolutionary approach isn't without its inherent challenges, often referred to as the "Serverless Paradox." Two prominent issues persistently faced by serverless architectures are cold start latency and the risk of vendor lock-in. Cold start latency refers to the delay experienced when a serverless function is inv…  ( 8 min )

At ITConnect, job seekers are at the heart of the platform. Our goal has always been to give them a clear, functional space where they can manage their profile, apply for jobs, and grow professionally — all from one place. That’s why we built the Worker Dashboard, a secure and focused panel for users with the “worker” role. What Users Can Do in the Dashboard Upload Their CV Add Education and Background Info Apply for Jobs Role-Based Access Control Technical Stack Behind It PHP + MySQL – backend logic and data storage Session handling – to identify logged-in users and enforce access rules Form validation & file upload security – for safe input handling HTML + CSS – for a clean, accessible user interface Key Lessons Learned CV Uploading: Requires strong validation (file size, format, naming) Application Logic: Needs checks to avoid duplicates or spam Access Control: Must be enforced at both front-end and back-end levels The worker dashboard is more than just a user panel — it’s a personalized space where real opportunities begin. We’re continuing to improve the experience based on user feedback and usage data.  ( 3 min )

Falling Into the CSS Rabbit Hole (Yes Again), Cleaning Up EC Links, and Planning Visual Improvements Today didn’t go quite as planned, but I still managed to check off a few important tasks. Yet Again, Stuck in CSS Tweaks Most of my time was unsurprisingly eaten up by CSS. I got caught up in adjusting the finer details of the design and before I knew it, hours had passed. It’s easy to fall into that CSS rabbit hole, but there’s something satisfying about refining the look and feel. Even small improvements can make the whole site feel more polished. Cleaning Up EC Links I took some time to clean up and reorganize the multiple EC links I had scattered across the site. It’s still a work in progress, but I’ve started creating a more consistent and intuitive user flow. Better structure means less confusion for the user, and that’s a win. Added New Pages from the Footer I created placeholder pages linked from the footer. There's no real content yet, but having the basic structure in place is a helpful step toward shaping the full site architecture. Sometimes, just laying the foundation helps bring clarity to what comes next. Next Up: Visual Improvements Right now, aside from the hero section, the site is pretty bare when it comes to images. To boost visual appeal, I’m planning to add more photographs and graphics. I’ll be experimenting with placement using the Z-pattern layout, which helps guide the viewer’s attention more naturally across the page. In Summary It wasn’t the most productive day in terms of raw output, but I did a lot of thinking and groundwork. Progress is progress—even when it feels slow. If you’re in the middle of building something too, hang in there. It’s all part of the process. Date: June 17, 2025 tags: portfolio, webdev, copywriting, ux, learning  ( 3 min )

After weeks of planning and designing, we finally made the big move — we started building ITConnect, our platform aiming to connect job seekers with companies in the tech world. We began by translating our interface from Figma into real, working code. But as anyone who has gone through this process knows, the transition from design to development comes with a whole new set of decisions and challenges. Week 1: Setting the Technical Foundation Creating the initial project layout Designing the navigation, footer, and main page sections Building a login system that supports two user types: companies and job seekers Setting up a database with key tables (users, companies, jobs, projects...) Implementing a file upload system for CVs and profile images Our Team & Workflow Erzana – backend logic and database structure Sumea – frontend development, bringing the Figma design to life Isme – authentication and platform security We collaborate daily using: GitHub for version control Discord for communication phpMyAdmin for managing the database Early Challenges & Lessons Learned Handling multiple user roles in a shared login system Securing access to pages based on user type Validating user input and profile data Safely storing uploaded files These problems helped us grow technically and work better as a team. What’s Coming Next? Building a company dashboard to manage job listings and applications Creating a worker dashboard for profiles and CV management Adding a section for freelance project applications Integrating a calendar feature for interviews and meetings We’re excited to keep sharing our progress and the lessons we’re learning along the way!  ( 3 min )

After carefully completing our project design in Figma, we thought the hardest part was behind us. But as soon as it was time to turn the design into a working product, we faced an unexpected challenge: We weren’t sure which technical direction to take. Each of us had different ideas. Some preferred a simpler and more straightforward approach, while others suggested a more modern and flexible solution. We spent time discussing, weighing the pros and cons of each option. What we learned is that this phase of the project requires not just technical knowledge, but also teamwork, compromise, and a shared vision of what we’re trying to build. In the end, we made a decision that felt right for us—as a team and for the goals of the project. In the next post, we’ll share more about the implementation process and the lessons we learned along the way.  ( 3 min )

At 8 PM, I was plating the second-to-last course of a wine dinner for 70 guests. At 3 AM, I was spinning up virtual machines and tearing apart old laptops. I’ve been cooking for as long as I can remember. When real life hit, I jumped straight into the kitchen — and almost never looked back. I tried a few other jobs here and there, but nothing ever really stuck. They paid the bills, sure, but they didn’t interest me. Cooking, though? I had the skills. I could make decent money doing it, and I loved it — so dealing with the chaos and the long hours felt worth it. But somewhere in the middle of all that, something shifted. I’d had a few conversations about IT over the years. My father-in-law teaches it and manages one of the server rooms at Promedica Hospital. Naturally, he likes to talk shop…  ( 7 min )

How we turned our idea into an interactive and intuitive user experience. When we started building ITConnect, we didn’t just want a platform that works. And that’s where design comes in. From Idea to Interface How can a student quickly find a job or a freelance project? The Home Page: The First Impression At the top, we placed a Hero Section with: A bold statement of our mission Testimonials from students who’ve found work and companies who’ve found talent — real success stories that build trust. Two large cards/buttons: Company Dashboard — Smart, Searchable, Simple A search bar with filters by skills, location, experience, and programming languages A profile page that includes: “Recommended for You” section — suggestions based on activity and profile Collaborate in real-time, no matter where we were What’s Next? But Figma isn’t done yet — as we grow, we’ll keep testing, adjusting, and iterating our UI based on real user feedback.

A student-driven project aiming to bridge the gap between young IT professionals and the companies that need them. Technology is not just code and algorithms. It’s opportunity. It’s connection. This is our idea. And this is our story. Why did we decide to create this platform? At the same time, companies are looking for talent — developers, designers, network engineers — but often don’t know where to find them easily. So, we asked ourselves: What if there was a simple, smart platform that connects both sides efficiently? What is ITConnect? IT talents (students, junior devs, freelancers) can build profiles, apply for jobs or projects, and grow their careers And we’re proud to say: this is being built by three Albanian students, from the ground up.  ( 3 min )

在发布我们的 SDK 时，一个时常需要考虑的问题：我们的新版本 SDK 应该支持哪些“版本”？ 这里的“版本”指代很多的东西，比如： 哪些型号的硬件，如 Intel vs Apple M 或者有没有 LiDAR 和 GPS 的设备 最低的可以用于开发的 macOS 版本 最低的可部署的 iOS 版本 最低可用于开发的 Swift 编译器以及 Swift API 对应的版本，如 4.3，5.0，6.0 等等 …… 作为苹果开发者很幸运：苹果公司和 macOS 已经尽量流线化整条产品线，作为苹果开发者毋需过多关注产品的兼容性——想想过去的 Windows 开发者要一直后向兼容到 Windows95，或者 Android 开发者不仅要兼容到 Android 4.0 还要在各种奇形怪状、性能高低的设备上测试，就庆幸自己手上的活儿已经足够简单；但发布时需要考虑的版本矩阵、排列组合，倒也并非一目了然。 苹果官方文档在这个页面上列出了对应的版本匹配，以方便专业开发者更好地厘清版本号的关联：https://developer.apple.com/support/xcode/ 对于我们 SDK 而言，大体上的策略是每年 iOS 升级为版本 n，则兼容 n, n - 1, n - 2 三个版本。而 Xcode 基本目前也是一年一个大版本号，我们也就秉承着“新的 major 版本 Xcode n.0 发布后的我们 SDK 的第一次更新，升级至要求当前 Xcode n.0 大版本”这样的策略。 这几乎已经足够简单明了，但还是有个小的不足—— 由于 Xcode 每年发布一个 major 大版本后 (Xcode 16.0)，通常有四到五次 minor 小版本的更新 (Xcode 16.1 - Xcode 16.4)，这就要求我们随时跟进 Xcode 更新，确保新的工具链依旧能开发、编译 SDK。同时，还要确保支持的最低版本 Xcode，不会因为 SDK 误用新引入的功能，而无法依赖引用它。因此，团队里几乎每一个开发者，都要安装至少三个版本的 Xcode： Minimum requirement version, e.g., Xcode 16.0 (16A242d) Current released version, e.g. Xcode 16.3 (16E140) Next beta version, e.g., Xcode 16.4 Beta (16F1t) (Before WWDC) or Xcode 26.0 Beta (17A5241e) (after WWDC) 有时，因为切换 Xcode 版本失误，会有不兼容的 API 符号溜进代码里面。好在有重重把关，总有人能在发布前测试发现这样的问题，确保发布的 SDK 不会在某些我们号称支持的版本上不能用。 然而，还是有点儿后怕——如果版本号的问题从 SDE 和 DevOps 眼皮底下都溜过去，最终被用户碰到，也算事故了。除了给每一台部署和测试的机器都装上三个版本的 Xcode，留一堆各种版本 iOS 的测试机以外，还能有什么更好更灵活的办法，来质检版本号呢？🤔  ( 3 min )

Cloudflare has announced an update to the enforcement order of its Gateway policies, rolling out progressively between July 14th and July 18th, 2025. The email from the Cloudflare Gateway Product Team explains that while this update will not weaken your security posture or change the traffic filtered by your policies, it does require a review of your configuration—particularly if you have HTTP policies in place. In the current model, Cloudflare Gateway evaluates DNS, then HTTP, and finally Network (Layer 4 Firewall) policies. After the update, the order will change to evaluate DNS first, followed by Network policies, and then HTTP policies. For example, if you have an HTTP policy that shows a block page for a “SaaS application” and a corresponding Network policy that silently blocks traffi…  ( 5 min )

We set out to build a system that could generate and run end-to-end tests automatically with predictable results and minimal input from the user. No recorded flows, no screenshots, no manual setup, just a URL. The system scans the page, builds a structured view using a serialized DOM, and generates test cases based on what it finds. We initially approached UI testing as a reinforcement learning (RL) problem. The idea was to train an agent to “see” a rendered web page: locate input fields and buttons based on screenshots, and act as a human user would. We fed screenshots into an RL model so it could learn where fields and click targets were. After a few iterations into the RL research, we began building a visual dataset and training a multimodal model that combined raw HTML (as text) with c…  ( 7 min )

When building backend APIs with Node.js—especially with frameworks like Express or NestJS—you’ll often find yourself handling user input via req.body, req.query, or req.params. But here’s a subtle trap many developers fall into: Mutating the request payload directly can cause hidden side effects. In this post, we’ll explore: What those side effects are, How Express and NestJS treat the request payload, When you should deep copy the payload, And best practices for safe and predictable request handling. When you mutate req.body, you're changing the original object passed through the entire request pipeline. This introduces side effects—unintended consequences in other parts of your app. // Middleware A req.body.username = req.body.username.trim().toLowerCase(); // Middleware B if (req.body.…  ( 4 min )

While Vercel only provides packages with the component for Next.js, Nuxt, and Astro, you can enable Image Optimization in any framework with the Vercel Build Output API. The first thing we need to do is tell Vercel that we want to use the Image Optimization API. To do that, we need to modify the bundler to add additional parameters to the .vercel/output/config.json file after the build. TanStack Start uses Nitro under the hood, and it provides an easy way to do this.

A psychologically-aware Claude is a safer, clearer Claude. I injected a 7-number psychology vector (≈ 50 bytes) into Claude Sonnet’s system prompt. It boosted empathy, risk calibration, and action clarity. In a blind A-B, Claude preferred the vector reply 12-1 (plus one tie). See screenshot for before-after responses and σ-scores. Receptiviti’s API returns 200 quantitative signals for any chunk of text. For this demo I used just seven: emotional awareness risk tolerance conscientiousness analytical thinking affiliation drive openness authenticity Those numbers are normalised (−1 σ to +1 σ) and squeezed into one comma-separated line: [psyvec: -0.2,+0.8,+0.4,-0.5,+0.6,-0.1,+0.3] Place that directly after your system role. It costs virtually zero extra tokens at inference time. • Gemini-style went from generic to empathy-tuned reply Plug-and-play: no model fine-tune, no extra GPUs, works in any prompt flow, vector replies felt more personal Capture ~350 words of user text. Send it to /analyze on the Receptiviti API. Select a subset of salient measures (start with the seven above). Build a psyche vector string and prepend it to your next Claude call.  ( 3 min )

What is git? Git is a distributed version control system, which means that a local clone of the project is a complete version control repository. These fully functional local repositories make it easy to work offline or remotely. Developers commit their work locally, and then sync their copy of the repository with the copy on the server. This paradigm differs from centralized version control where clients must synchronize code with a server before creating new versions of code. Version control, also known as source control, is the practice of tracking and managing changes to software code. Version control systems are software tools that help software teams manage changes to source code over time. As development environments have accelerated, version control systems help software teams wo…  ( 4 min )

Developers deserve to have fun. There was a time when the internet felt magical. I remember going to the library just to create a character on The Doll Palace. At home, I'd spend hours changing fonts with WordArt. But as I grew up, the industry did too. We've shifted away from marquees and glittery cursors. Grown-up me started using ones and zeros to build reliable systems for insurance, banking, and healthcare companies. There's pride in that, but it's harder to justify doing something just because it's fun. That's why I tapped into my inner child and used Goose to build a UI that reacts to users' emotions.

Working on a client project in a distant country recently presented an interesting challenge. They had a strict requirement, I needed to upload my progress every week so they could monitor the project in real-time. I agreed, though with some initial reluctance. This setup quickly revealed unexpected bugs whenever I moved my code from my local development environment to the live server. One particular issue left me truly dumbfounded: the PHPMailer-powered "send mail" feature worked flawlessly on my local machine, but consistently threw errors on the live server. The solution was simple once identified: I had to rename the PHPMailer folder on the live server to match the exact capitalization used in my require statements. Once I changed it to PHPMailer, everything worked perfectly. If you ever encounter similar "file not found" errors when deploying from a Windows to a Linux environment, always ensure your file and folder naming conventions are precise and consistent down to the capitalization. Adhering to conventional naming standards across both servers will save you countless hours of debugging and a lot of stress.  ( 3 min )

Tools I Used: Streamlit to build the interactive user interface LangChain to structure the prompt and manage the AI response OpenAI’s GPT-3.5 Turbo to generate the announcer script ElevenLabs to convert text into realistic speech Python-dotenv to securely load my API key Each project in this series helps me build my skills in both coding and AI while keeping it fun by focusing on basketball. I’m looking forward to continuing this series with new features and ideas. As always, feedback is appreciated.

"Your database is a ledger, not a scrapbook." Most apps treat data like a blackboard—constantly erasing and rewriting. CRUD (Create, Read, Update, Delete) is simple… until: You need to audit changes ("Who set this price to $0?") You want to replay history ("How did the system behave last Tuesday?") You accidentally overwrite data with no recovery path. Event Sourcing flips the script: Instead of storing state, you store events that led to that state. But when does it actually matter? Let’s compare. 1. The Core Difference CRUD (Traditional Rails) # Update a user’s balance directly user.update!(balance: 100) # Problem: History is lost # What was the balance before? Who changed it? Why? Event Sourcing # Record an event instead event = BalanceAdjusted.new( user_id: u…  ( 4 min )

I wasn’t sure if I should write this, and share these thoughts mmm... but hey, soon no one will be reading humans anyway. No original ideas, just AI-generated content everywhere. So yeah, a bit of a rant this time, but what can you do, that’s the vibe these days. Let’s look at what happens when you rely too much on AI early in your career. And why companies, and finally managers, are starting to notice. And we are not so happy about it. Disclaimer: I’m not anti-AI. I use tons of AI-based tools myself 😉 You’ve done some courses, maybe a bootcamp. You know your way around Python, SQL, and you’ve started doing take-home tasks. And then you discover ChatGPT.

As a developer who’s been coding for 15+ years, I’ve recently shared my excitement about AI IDE's in general, and after trying a bunch of them my main editor for some time now is definitely Cursor. Disclaimer: this is not a paid promotion (in fact I'm the one paying Cursor their Pro Plan), it's just my honest opinion on using it and my thoughts about the experience. This AI powered code editor, built as a fork of Visual Studio Code, has transformed how I work, and I want to dive deeper into that on this article. Here’s how I’ve been leveraging Cursor, why it feels like cheating, and why my foundational skills remain key. AI won’t drive the project for you. It’s fast, confident, and occasionally dead wrong.

Ok so I've now been using Claude Code for a little over a week. It has supplanted Cursor as my primary tool for AI assisted coding tasks, and the transition was very rapid. In fact, I'm not sure I'm going to continue to pay for Cursor. One of the things that I discovered early on with Cursor was that it would frequently get "lost" in my monorepo. If it ever wanted to run an external command, such as installing another npm dependency, it would do it in the wrong directory (usually the repository root). The same thing would happen when trying to run the linter, or unit tests, etc. Almost every single time, I had to explicitly tell it to run a command in a given subdirectory, or just reject the command altogether and run it myself. To address this problem, I began running searpate Cursor in…  ( 7 min )

Backend Developer, you've probably had this situation happen: You finish building your API. Everything works perfectly. You test it ten times on Postman. Then your Frontend Developer shows up frustrated: “Something’s not working... the app is freezing!” You check the code and see that your API always returns 200 OK, even when there's an error — with a JSON message saying "Something went wrong." Meanwhile, the frontend is expecting something like 400 Bad Request to show an error message properly. You're both speaking JSON… but you're not speaking the same language. HTTP Status Codes come in. HTTP status codes are standardized codes sent by the server to indicate the result of a client's request. They aren't just random numbers. They're the core communication language between frontend and ba…  ( 5 min )

You're building with AI — maybe a chatbot, an agent, a writing assistant, or something more experimental. The code is coming together, the idea is taking shape… and then the real question hits: “Which model should I actually use?” Suddenly, you’re lost in a jungle of names: GPT-4, GROK, Mistral, Claude, LLaMA, Gemma... Some are open source. Some are locked behind APIs. Some are fast, others smart, all of them marketed like they’re magic. And every source seems to offer conflicting advice. The truth is: It’s not about picking the best model in the world — it’s about picking the best model for your job.

From clean code to clean systems — my journey into system design and the architectural insights that changed the way I build. At the end of May, I made a conscious shift in my learning journey — I dove deep into System Design. It became clear that writing clean, scalable, and maintainable code goes far beyond just knowing a language or framework — it starts with how your entire system is designed. I’ve always believed in the cycle of learn–unlearn–relearn. So I paused, re-evaluated, and redirected my focus toward understanding: What is system design? Why does it matter? When do we need it? This shift opened my eyes to the architectural thinking behind every successful product. I started with: Architecture patterns PRD (Product Requirements Document) — understanding how clear documentation shapes the development lifecycle. Next came Microservices Architecture — and that’s when things got exciting. I explored: Architectural styles and service boundaries API Gateway and NGINX for routing, load balancing, and security The role of asynchronous communication in system performance Version control and project organization also matter. I studied: Monorepo: Single repository for all services/projects Polyrepo: Independent repositories for each service/module Both have their strengths. Knowing when to use one can streamline collaboration and CI/CD processes. I wrapped up with: RBAC (Role-Based Access Control) to structure user permissions ERD (Entity Relationship Diagrams) to visualize data models and relationships across the system To build systems that are clean, efficient, and easy to evolve. System design is helping me see how everything connects — from requirements to deployment. And I’m just getting started. 💬 Are you also diving into system design? Share your experience or favorite resources in the comments! 📌 Connect with me on DEV — that’s where I’ll be documenting the journey further.  ( 4 min )

While this enables a form of non-local exit, TypeScript lacks the ability to statically type these thrown errors, compromising type safety. To address this, the Result type offers a way to explicitly model success and failure in a function's return value. Libraries such as neverthrow, effect-ts, and fp-ts are commonly used to introduce this pattern into TypeScript. However, each of these libraries has trade-offs. While neverthrow is relatively simple and user-friendly, it is no longer actively maintained—many pull requests have been left unreviewed for months. On the other hand, effect-ts and fp-ts offer powerful features but come with high complexity and large bundle sizes, which can be overk…  ( 4 min )

The goal If you want to run PostgreSQL in production, setting up transport layer security (TLS) is a must in order to prevent man in the middle attacks. In this step by step guide I will show you, how you can connect to your database securely using your own local certificate authority. If you need an in depth explanation of all settings you can checkout the official documentation on how to setup TLS in PostgreSQL. In this example we will ONLY allow encrypted connections and we will set sslmode to verify-full which is the strictest possible connection setting in PostgreSQL. You need Docker installed on your machine. If you are on a Mac or windows, make sure to install Docker desktop and have it running in the background. Verify Docker is running by typing docker ps in your terminal. You s…  ( 7 min )

Você já sonhou em se mudar para outro país — começar do zero em um lugar novo, com novas oportunidades e uma melhor qualidade de vida? Para muitos engenheiros de software, a ideia de trabalhar no exterior é ao mesmo tempo empolgante e intimidadora. Eu sei, porque já passei por isso. Nasci e cresci no Brasil, um país em desenvolvimento onde, mesmo como engenheiro de software, a vida traz seus próprios desafios. Embora a profissão possa oferecer um salário confortável, o dia a dia era frequentemente ofuscado por preocupações com segurança — coisas simples como usar o celular em público ou caminhar para casa à noite se tornavam fontes de ansiedade.

Anchoring is one of the most critical aspects of boating, especially for adventurers who explore diverse waters. But what makes the process smoother and more efficient? One key component: the bow roller. 🛥 What Is a Bow Roller? A bow roller is a metal or polymer fitting mounted on the bow of a boat, designed to guide the anchor rode and anchor chain during deployment and retrieval. It allows your anchor to move freely without damaging the boat or creating friction on the hull. 🔧 Types of Bow Rollers Single Bow Roller – Ideal for smaller boats or occasional anchoring. Double Bow Roller – Allows dual-anchor setups. Self-Launching Bow Roller – Uses gravity and angles to deploy the anchor with minimal effort. Adjustable Bow Roller – For larger vessels needing multi-position adjustment. 🔍 Pro Tip: Always choose a roller that suits your anchor type (Danforth, Bruce, Plow, etc.) 🌊 Why Bow Rollers Matter Prevents anchor chain damage to the hull Eases anchor retrieval with windlasses Enhances anchoring safety during rough waters Keeps the anchor secure and stable when underway 🛠 How to Install a Bow Roller Choose a marine-grade stainless steel or aluminum roller. Align the roller with your anchor locker and chain path. Secure it using corrosion-resistant bolts and marine adhesive. Test it with your anchor before hitting the waters. ** Best Bow Rollers for 2025** Lewmar Bow Rollers Mantus Marine Anchor Rollers Sea-Dog Line Bow Rollers These brands offer durability, design flexibility, and compatibility with different anchor types.  ( 3 min )

BioChatter is a new open source Python package (v0.11.1 released June 6 2025) designed to bring conversational AI into biomedical research workflows. This library provides a clean backend interface for integrating large language models with biological knowledge graphs via BioCypher and common biomedical tasks. It abstracts away provider specific details with a unified API for sending prompts, retrieving structured outputs, and handling model completion logic over multiple LLMs. Install the package via pip: pip install biochatter Then initialize and call a model: from biochatter import BioChatter bc = BioChatter(provider="openai", api_key="YOUR_KEY") response = bc.ask("List key genes involved in oxidative stress response") print(response) BioChatter converts your question into a structured query, invokes an LLM, and formats the response as JSON or a DataFrame. It also supports: integration with BioCypher for knowledge graph grounding evaluation metrics such as accuracy and F1 for test sets model agnostic chaining to compare GPT 4, LLaMA, and others BioChatter streamlines building apps like gene disease extractors, literature summarizers, or dialog agents for molecular data without scaffolding each component manually. The built in evaluation framework lowers the barrier for reproducible benchmarks in biomedical NLP. Researchers working on hypothesis generation, clinical extractive tasks, or biomedical QA now have an easy way to prototype and compare conversational AI pipelines. Explore documentation and examples at the GitHub repo. Start experimenting by connecting to your lab’s knowledge graph or loading custom biomedical prompts. Share your use cases and help grow the community. BioChatter lays the foundation for more conversational and data driven tools in biology, offering a versatile core for integrating LLMs thoughtfully into scientific workflows.

For years, Cloudflare’s WAF has been my go-to solution for protecting web applications. It’s easy to use, has strong threat intelligence, and offers features like rate limiting, bot mitigation, and challenge pages. However, it’s not without downsides—especially for those of us who prefer control, transparency, or simply want to avoid recurring costs. Recently, I set out to find a self-hosted alternative that could meet my needs without compromising on protection. After testing several options, I discovered SafeLine, a powerful, open-source Web Application Firewall that has now fully replaced Cloudflare WAF in my stack. Here’s how and why.

The Map state of AWS Step Functions returns an array of arrays as a result. For further processing, we often need to flatten this result into a simple one-dimensional flat array. With JSONPath, this can be accomplished using the [*] expression as described in the AWS docs: "ResultSelector": { "flattenArray.$": "$[*][*]" } AWS docs for JSONPath Recently, AWS Step Functions introduced JSONata as an alternative query language to JSONPath. However, since this feature is quite new, you won't find much information on how to accomplish the same with JSONata. At least, this section didn't make it into the AWS docs for JSONata yet. In JSONata you can use the .* expression to flatten an array of arrays: JSONata Exerciser However, you must be aware that this expression returns nothing if the result array is empty: JSONata Exerciser In JSONata, you can usually append [] to an expression to cast the result to an array, even if it has only one value: JSONata Exerciser However, this trick doesn't work in this case as both [].* and .*[] will return nothing: JSONata Exerciser The correct way to handle it is a simple ternary condition using the $exists() function: JSONata Exerciser If the expression $exists(states.result.*) evaluates to nothing (falsy value), it will return an empty array as a fallback. You may ask yourself if there is a shorter version using a short circuit || or null coalescing ?? operator like in JavaScript: states.result.* ?? []. Unfortunately, this remains an open issue.  ( 3 min )

Next day's focus was all about TypeScript, and it opened up a new way of thinking about code for me. I’ve always been comfortable with JavaScript, but this statically typed superset challenged me in a good way. We started by covering the basics — type annotations for variables, function parameters, and return values. Then we moved into more advanced concepts like interfaces, type aliases, and optional vs required properties. It felt a little rigid at first, especially coming from JavaScript's flexibility, but the benefits quickly became clear. I built a simple to-do app and used TypeScript to define the shape of each task, enforce valid input, and handle errors gracefully. By the end, my IDE was catching mistakes before I even ran the code — something JS never gave me. That sense of confidence and clarity was super motivating. One thing that stuck with me: “TypeScript makes you design your data before writing the code.” That discipline made my logic cleaner and more reusable. It also made debugging easier because everything was more predictable. I can already tell that TypeScript will be central to how I build both backend and frontend features going forward — and I’m actually excited about that. 💬 Question for Readers: How has using TypeScript changed the way you think about writing JavaScript? Did it help you avoid bugs, or did the strict typing feel like a barrier at first?  ( 3 min )

Leaderboards are everywhere in AI these days. They help us compare models, track progress, and decide which ones are worth our time and resources. But sometimes, a model's top score might raise an eyebrow—almost like it knew the answers ahead of time. It’s easy to assume the highest-ranked models are the smartest or most capable. But in reality, there’s a subtle issue that can throw these rankings off. And while it might sound like cutting corners, it’s not always that simple—or even wrong. In this article, we’ll take a closer look at how this issue impacts model evaluations, why it’s more common than you might think, and how, when handled carefully, it can actually make models more useful in practice.

Passing argument by object reference, you will not understand in coding level it more of memory thing how memory work for passing an argument I will give you two example from python and C. Creating my_box: Python creates a dictionary {"item": "old toy"} at some memory address, say 0x1234. my_box is a variable that holds the reference 0x1234 (the address of the dictionary). Calling change_box(my_box): The function change_box gets a copy of the reference 0x1234, stored in its parameter box. Now, both my_box (outside) and box (inside the function) point to the same dictionary at 0x1234. 3.Modifying the Object: When box["item"] = "new toy" runs, it modifies the dictionary at 0x1234. Since my_box still points to 0x1234, it sees the change ({"item": "new toy"}). What If We Reassign? (Uncomment the line): If you uncomment box = {"item": "another box"}, Python creates a new dictionary at a different address, say 0x5678. Now, box points to 0x5678, but my_box still points to 0x1234. The original dictionary (my_box) remains unchanged. num is stored at some memory address, say 0x1000, with value 10. The function try_to_change gets a copy of num’s value (x = 10) stored at a different address, say 0x2000. Changing x only affects 0x2000, not 0x1000.

A website can load its content in a flash, but if users can't click, scroll, or interact with it, the experience feels broken.

🎯 Objective Demonstrate how to exploit a blind SQL injection vulnerability when: The application does not return any visible output. Error messages are suppressed or handled gracefully. No conditional response difference is observed. In such cases, we can use time-based blind SQL injection — where the attacker forces the database to wait (delay) for a certain amount of time depending on whether an injected condition is TRUE or FALSE. This delay allows us to infer sensitive data one character at a time based on how long it takes for the HTTP response to arrive.

Scenario In my project, we have over 10+ users with access keys. Most of the access keys were 300–400 days old. Having access keys lying around for a long period poses a security risk, which is unacceptable. They’re not just a minor security issue — they’re multimillion-dollar liabilities. The issue I can see is that no one remembers to rotate the access keys, so I thought of building a Lambda function that could remind the team to rotate the keys after a certain number of days. Different organizations enforce varying rotation policies — some require rotation every 30 days, others allow 60 or 90 days before access keys must be refreshed. My solution needed to accommodate these different requirements while being easy to deploy and maintain. In this blog post, I’ll walk you through the com…  ( 9 min )

Caching is difficult to get right and often means you need to pull in additional frameworks into your code. Fine tuning the balance between performance and data freshness takes time and experience. In case of User-Agent integrations (for example, an application UI running in your user’s browser), it is even more crucial, as the User-Agent is rarely under your control and yet demands fast response times. This is why often I opt to provide cache recommendations for the service side in many cases. One such example of this in the product I work heavily with Authress. That doesn’t mean you can’t cache returned values for longer. I'm going to use Authress as example for caching, so a quick summary might make sense. Authress provides login and access control for the applications you write. This m…  ( 9 min )

Decoding VLMs: A Simple Explanation of Vision-Language Models In the rapidly evolving landscape of artificial intelligence, Vision-Language Models (VLMs) represent a significant leap forward, bridging the previously distinct domains of computer vision and natural language processing. Unlike earlier AI systems that excelled at either “seeing” (analyzing images) or “understanding” (processing text), VLMs are multimodal powerhouses, capable of seamlessly interpreting and generating content that incorporates both visual and linguistic information. At their core, VLMs typically integrate a sophisticated vision encoder, which extracts meaningful features from images or videos, with a powerful language model (often a large language model or LLM) that understands and generates human-like text.

In the mobile-first world, users expect seamless navigation between apps and websites. Deep linking bridges that gap by allowing you to link directly to specific content within a mobile app, and in Flutter, it's easier than ever to implement. In this blog, we’ll dive into what deep linking is, why it matters, and how to implement it in your Flutter application. Deep Linking refers to the practice of launching an app and opening a specific page (or route) within it using a URL. For example, clicking a link like myapp://product/123 opens the product detail page for item ID 123 in your app. There are three main types of deep links: 1. Traditional Deep Links: Work if the app is already installed. 2. Deferred Deep Links: Work even if the app isn’t installed; the user is taken to the app store f…  ( 7 min )

Streamlining Design to Code with AI AI is changing how we build Android apps, especially when it comes to turning designs into actual code. It's not about replacing developers, but more about giving us tools to work faster and smarter. I've been playing around with some AI-powered solutions, and it's pretty wild how much time they can save. Automating UI Generation for Kotlin One of the coolest things is how AI can now generate UI code directly from design mockups. Forget manually coding every button and layout – AI can analyze a design and spit out the Kotlin code for it. It's not always perfect, of course. You still need to tweak things and make sure everything is pixel-perfect, but it gets you a huge head start. I remember spending hours just setting up basic layouts, and now AI can do…  ( 5 min )

A website passes an automated accessibility scan with flying colors. The dashboard shows zero errors, and you're feeling confident. But when a screen reader user attempts to navigate the site-or someone tries to operate it with a keyboard only-the experience falls apart. Automated accessibility testing tools are useful, no doubt. They speed up checks, catch many critical issues, and help enforce web standards like WCAG. But they’re not infallible. Many nuanced and contextual issues fly under the radar, and relying on automation alone can give a false sense of compliance. To build truly inclusive digital experiences, human insight is essential.

Hey folks! TL;DR: Rive is a big deal for designers, and developers. I've been experimenting with motion design & micro interactions lately. As context, I'm a full stack dev with a background in design & motion. I've always dreamed about a way to make animations in After Effects that are NOT just meant to be exported as .mp4 files but actual interactive animations I could use on my websites or apps. Back in the day, I messed around with Lottie using the Bodymovin plugin for After Effets in order to achieve that. I'm not gonna lie: it "worked" but it was very bad DX and not really efficient (big JSON animation file). -- 5 years later -- I stumbled upon Rive and started to experiment with it, and wow it's exactly what I would dream about: An animation tool that can export lightweight and interactive animations with full control through code. The export is a .riv binary file that is loaded by the Rive SDK. Starting from that, you can interact with your data bindings and inputs set in Rive in plain JS, enabling infinite possibilities! My personal take is that with the incoming flood of average software due to AI, design delight will be back. And this Rive thing is probably a big deal for the future. Let me know your thoughts!

Senior developers face a productivity crisis. Research shows developers lose 8+ hours weekly to inefficiencies, with only 44% of managers aware of these issues. Context switching affects 43% of developers, while early-career developers doing 15 hours of deep work weekly advance faster than those doing only 4 hours. Traditional time management fails when you need to debug complex systems or design scalable architectures. The Pomodoro Technique works for shallow tasks, but senior-level challenges demand sustained attention. This is where the 4-hour focus block transforms your development workflow. Why 4 Hours?

One of the recurring issues many companies face is the struggle to optimize their financial systems. Delayed transactions and complex integrations often happen because there’s no real-time data coming in from customers. In most cases, this is due to financial information being locked away in separate systems. On top of that, customers expect smooth and seamless transactions, even as their needs continue to change. This growing demand creates more pressure on businesses to keep up. To resolve these challenges, open banking was introduced. It's a model that gives integrators more control over financial data, making it easier for businesses to deliver fast, secure, and personalized financial experiences. And it’s not just for financial service providers. Traditional companies can also tap int…  ( 9 min )

As developers, we often create temporary files or debug utilities during development. But what if you don’t want these debug files: to show up in git status or accidentally be committed yet you don’t want to edit .gitignore — especially in a shared codebase .git/info/exclude Git has a local-only ignore file, specific to your repo clone located at .git/info/exclude Anything you add there behaves just like .gitignore, but: It’s not version-controlled It won’t affect your teammates It’s perfect for one-off debug or temp files Why I Use This I had a helper function called useRenderCount() to count component renders while debugging a React app. I didn’t want to commit it by accident or to pollute the shared .gitignore Adding it to .git/info/exclude let me: keep the file locally use it freely never worry about it ending up in Git  ( 3 min )

As someone who’s built full-stack projects (React + Node + Mongo + Auth, APIs, UI logic, etc), I thought jumping into AI/ML would just be another tech stack to “𝘭𝘦𝘢𝘳𝘯 𝘢𝘯𝘥 𝘣𝘶𝘪𝘭𝘥”. But I was wrong.

Early computers, such as the ENIAC and the UNIVAC, had extremely limited resources by today's standards. Memory was scarce and expensive, often measured in kilobytes, and processors operated at speeds measured in kilohertz. For instance, the ENIAC had a memory capacity of about 20 words, each 10 decimal digits long, and operated at a clock speed of 100 kHz. These limitations necessitated a meticulous approach to software development, where every byte and clock cycle counted. Developers often wrote programs directly in machine code or assembly language to maximize efficiency. Machine code consists of binary instructions specific to the hardware, while assembly language uses mnemonics to represent these instructions. Both approaches allowed for precise control over hardware resources. For e…  ( 5 min )

Most developers are still building apps like it’s 2015. Jumping between Figma, Notion, Bubble, and ChatGPT. More hours. More tabs. More burnout. But in 2025, the smartest builders are taking a different path. They don’t hire teams. They hire one smart AI that works like a partner. From Code Monkey to Creative Director You wouldn’t hire a full-stack dev, a content strategist, a UX writer, and a project manager just to ship an MVP. You’d go broke before launching.

I used to have a tool for everything. One for debugging. The more tools I added, the more fragmented my workflow became. I wasn’t developing faster. That’s when I realized… I didn’t need more tools. I needed one smart assistant that thinks like a dev. The Developer’s Bottleneck Isn’t Code — It’s Context Switching You Google a Stack Overflow answer Bounce into VS Code Copy from ChatGPT Jump to Notion or Slack Rewrite the same function three times You’re not slow because you don’t know what to do. Enter: My AI Dev Stack (Without the Stack) Here’s what changed: One prompt replaces 5 tools I debug code, write docs, generate UI, and brainstorm systems — in one place It remembers my logic Crompt stores my dev patterns, past code snippets, and naming conventions so I never start from scratch It thinks in systems, not snippets Most AI gives you one-off answers. Crompt builds with you like a co-pilot who’s in sync with your style and stack Real-World Use Cases I Run Daily Write and optimize backend functions for async workflows Translate pseudocode into clean, production-level syntax Audit entire code blocks for bugs and performance Explain complex logic in plain English (great for team onboarding) Auto-generate documentation based on real code context The Hidden Benefit: Focus One platform means fewer tabs, fewer decisions, and more uninterrupted flow. I now spend more time solving real problems — and less time stitching my workflow together. No more prompt recycling. Developers Don’t Need More Power. They Need More Leverage. It’s here to: Accelerate the thinking process Protect your mental energy Build systems that scale with your growth That’s what Crompt AI does. It’s not a chatbot with code wrappers. Try the Stack That Replaces Your Stack Start building with one platform that evolves with you. Crompt AI is the all-in-one AI assistant that helps you think, code, ship, and optimize — like a founder-engineer, not a task-runner. Replace the clutter.

Imagine your toy box. You have one in your room. Your brother has one in his room. You can't reach into his toy box, and he can't reach into yours. That's scope. Now, let’s say your toy robot remembers your name even when you leave the room. That’s closure. Let’s go a bit deeper (but still like you're 5): Scope means "who can see what." function playRoom() { let toy = "robot"; console.log(toy); // ✅ can see robot } console.log(toy); // ❌ error, can't see robot Why error? Because toy is in the playRoom. Outside can't see inside. Closure means a function remembers things from where it was born. function makeToy() { let toyName = "Buzz"; return function() { console.log("Playing with " + toyName); }; } let play = makeToy(); play(); // ✅ "Playing with Buzz" Even though makeToy() is done, the inside function remembers toyName. That’s a closure. Scope: "You can only use your toys in your room." Closure: "You made a magic toy that remembers your name, even if you take it outside." Helps avoid bugs. Lets us write smart code like hiding secrets or making factories. Used in React hooks, event handlers, and more. Scope = "Where can I see this?" Closure = "I remember where I came from." Want to test it? Try these: // Challenge 1 function box() { let secret = "shhh"; return function() { console.log(secret); } } box()(); // What will it print? // Challenge 2 let a = 10; function outer() { let a = 20; function inner() { console.log(a); } return inner; } let result = outer(); result(); // Guess the output! Keep playing with the code. Think of scopes as rooms and closures as memory toys. Happy coding like a 5-year-old genius! 🎉  ( 3 min )

Hi all! Today I continued learning about the video element and all its attributes. We need an attribute called controls enabled in order for the video to play....also we need to mention the type of video format so that the browser can render it accordingly. We can also give attributes like autoplay muted and loop to the source tag so the the video plays automatically each time the website is loaded. But some users might find autoplay as a form of violation of their privacy and so we must try and avoid using autoplay. Youtube video in the website. This can be done using the iframe tag and the url can be obtained by selecting the share option in the desired Youtube video and copying the code given under embed tab into the iframe. Similar to regular video we can also use autoplay and mute options in this. However these should not be written as seperate attributes but should be written at the end of the iframe URL address with their values set to 1. So that's all for today.....see you all in the next post!  ( 3 min )

From Tool Chaos to Development Zen: A Developer's Journey to the Perfect Workflow Kruti for Teamcamp ・ Jun 16  ( 2 min )

Recent research has cast new light on the limitations of modern AI “reasoning” models. Apple’s 2025 paper The Illusion of Thinking shows that today’s Large Reasoning Models (LRMs) — LLMs that generate chain-of-thought or “thinking” steps — often fail on complex problems. In controlled puzzle experiments, frontier LRMs exhibited a complete accuracy collapse beyond a complexity threshold. In other words, after a certain level of difficulty, their answers become no better than random. Equally striking is their counter-intuitive effort scaling: LRMs ramp up their chain-of-thought as a problem grows harder, but only up to a point. Beyond that, they actually give up — even when the token budget remains ample, their detailed reasoning steps abruptly shrink. These findings suggest a fundamental ga…  ( 8 min )

Welcome to Day 9 of our FastAPI Zero to Hero series! Today we unlock one of the most powerful (yet misunderstood) tools in modern web development — Async Programming. Writing non-blocking code can be accomplished through async programming. This implies that your program doesn't wait for sluggish operations (such as file reads or API requests) to complete before continuing. Alternatively, it can work on other projects in the background when those tasks finish. You're cooking dinner 🍳 and waiting for the rice to boil. While it boils, do you just stare at the pot? Nope — you chop veggies or scroll through Instagram reels. That’s asynchronous behavior — you’re multitasking efficiently. Async is the engine behind that speed and FastAPI is built for speed. When a route is defined with async de…  ( 6 min )

Today, I made good progress in learning React by exploring some very important concepts: useState, the spread operator (...), and the map() function. These features are essential for building dynamic and interactive components in React. Below, I’ll share what I learned with simple explanations and examples. useState Hook – Managing State in Functional Components In React, state is used to store data that can change over time. The useState hook helps us add state to functional components. const [state, setState] = useState(initialValue); import React, { useState } from 'react'; function Counter() { const [count, setCount] = useState(0); return ( Count: {count} setCount(count + 1)}>Increase ( {fruit} ). The key is used to uniquely identify each element.  ( 3 min )

Table of Contents Introduction Understanding the as const keyword Conclusion In Typescript, type inference is powerful, but sometimes we need more control over the types in our code. This is where the as const keyword comes in. By using as const, we ensure that Typescript treats our values with specific types, preserving and using their exact value instead of generalising them. In this article, we'll explore how the as const keyword works and how it can enhance your development with Typescript Typescript uses broader types when inferring the type of a value. For example, when you declare a variable with a string, Typescript will infer the type as string, rather than the exact string value you assigned. However, using the as const, you are telling Typescript to treat the value as a con…  ( 5 min )

Hey everyone! 👋 I've put together a complete end-to-end CI/CD setup using: ✅ AWS CodePipeline ✅ AWS CodeBuild ✅ S3 for hosting a static website ✅ Separate unit testing stage before build If you're looking to test, build, and deploy your web app — automatically — using only AWS services, you’ll love this setup. 📌 Step-by-step setup for Running unit tests with a dedicated unit-test CodeBuild stage Building your app (React, Angular, Vue, etc.) Deploying the built files to an S3 bucket (static website hosting) Automating it all with AWS CodePipeline I’ve added a separate CodeBuild project that: Runs your test framework Fails early if tests don't pass ✅ Prevents broken code from moving to build or deploy stages Once tests pass, a second CodeBuild stage: Runs build Uploads the output (like dist/ or build/) to S3 S3 serves your static website via public endpoint or CloudFront 📁 GitHub Repo (Step-by-Step Instructions): cicd-codepipeline-GitHub Frontend developers deploying static apps DevOps engineers automating CI/CD pipelines Anyone exploring AWS CodeBuild, CodePipeline & S3!

“It’s just S3. What could go wrong?” If you’ve ever had this thought while deploying an app, building a static site, storing user uploads, or integrating backups, you're not alone. But you might also be unknowingly misusing one of the most powerful — and deceptively simple — services in the AWS ecosystem: Amazon S3 (Simple Storage Service). Yes, S3 — the Swiss Army knife of AWS. It sounds harmless, even elegant: a “bucket” where you store your files. But the truth is, most developers (up to 85%) are not using S3 the right way, especially at scale or in production-grade applications. From skyrocketing costs, broken performance, misconfigured security, to compliance nightmares — the misuse of S3 creates hidden dangers that quietly eat away at your infrastructure. The beauty and danger of S3 …  ( 7 min )

A junior developer's guide to understanding component execution strategies If you're just starting your frontend journey, you've probably heard terms like "compilation," "build process," and "bundling" thrown around.

AWS recently announced something awesome: CodeBuild now supports remote Docker servers! 🎉 But wait... what does that even mean? Let me explain with a simple example that anyone can follow 👇 Every time you cook pasta, you do the same steps: Boil water 🍲 Cut vegetables 🥕 Make the same sauce 🍅 Cook pasta 🍝 Now imagine doing this from scratch every single time — even if the recipe doesn't change! 😩 Wouldn't it be smarter if your kitchen assistant saved your sauce, chopped veggies, and hot water, so you could reuse them and cook faster? Before Every time AWS CodeBuild ran a Docker build, it started from zero. It downloaded everything again (base image, node modules, etc.) ⏳ Builds were slow, even for tiny changes. Now AWS provides a remote, invisible Docker server just for you. This server remembers your past Docker layers (cached!). Next time you build — it’s faster, because it reuses what didn’t change. 🚀 Your Dockerfile for a Node.js app: FROM node:20 COPY package.json . RUN npm install COPY . . CMD ["npm", "start"] First Build All steps run from scratch. ⏱️ Next Build Docker skips node:20 (already cached) Skips npm install (if package.json didn’t change) ✅ Only rebuilds what actually changed! Without Remote Server With Remote Server Always builds from scratch ❌ Reuses cached layers ✅ Slower CI/CD ⏳ Faster builds 🚀 More compute & network usage 💸 Efficient + cheaper 💡 Nope! 🎉 This feature is a game-changer for developers using AWS CodeBuild and Docker.

The integration of artificial intelligence into the workplace is rapidly evolving beyond simple automation. We are entering an era where AI is no longer just a tool but an active "teammate," fostering a new paradigm of "collaborative intelligence." This shift amplifies human intuition and creativity with AI's analytical prowess and efficiency, promising a transformative impact on how we work and innovate. Historically, AI has been perceived as a means to automate repetitive tasks, boosting individual productivity. However, advancements in large language models (LLMs), generative AI, and agentic AI are enabling systems to perform complex cognitive functions, learn, adapt, and even make autonomous decisions. This evolution positions AI as a true collaborator, a digital colleague capable of e…  ( 3 min )

This article aims to give software engineers a fast-track introduction—a practical guide to navigating and thriving in this new landscape. The mind map below outlines the flow of the article. We’ll start with how to use AI effectively, then move into how to build things with it, touching on key concepts along the way. Let’s dive in. When people talk about using AI, it's impossible not to bring up how it all started—ChatGPT was the moment generative AI rea…  ( 8 min )

📝 Note: I’m not an academic guru, just a developer navigating the world of research for the first time. Everything in this post comes from what I observed and learned the hard way. Use it as a perspective, not a prescription. When I decided to build RouteBastion (my SaaS platform for unified VRP solutions) as my Master’s Thesis, I thought the hard part would be the code, and boy, I was wrong. Entering the world of Academic Research and R&D while coming from a full-time software engineering background was a whole new game. Here's what I learned and what I wish someone had told me earlier. Let me break it down for you like I did for my friend Mark: Sometimes it’s easy: you find papers solving exactly your problem, cite them, highlight your difference. Sometimes it’s tricky: you find papers …  ( 5 min )

3405. Count the Number of Arrays with K Matching Adjacent Elements Difficulty: Hard Topics: Math, Combinatorics You are given three integers n, m, k. A good array arr of size n is defined as follows: Each element in arr is in the inclusive range [1, m]. Exactly k indices i (where 1 <= i < n) satisfy the condition arr[i - 1] == arr[i]. Return the number of good arrays that can be formed. Since the answer may be very large, return it modulo 109 + 7. Example 1: Input: n = 3, m = 2, k = 1 Output: 4 Explanation: There are 4 good arrays. They are [1, 1, 2], [1, 2, 2], [2, 1, 1] and [2, 2, 1]. Hence, the answer is 4.

En la integración de sistemas, es común tener que consultar grandes volúmenes de información a servicios externos que tienen límites estrictos o, simplemente, servicios de terceros donde no tenemos la posibilidad de solicitar un escalamiento. En los últimos años, he tenido la "oportunidad" de desarrollar soluciones para migraciones de datos con volúmenes entre 1.000 y 300.000 registros, con datos que dependen de otros sistemas, en su mayoría legacy. Si a eso le sumamos que muchos de estos no podían ser escalados para soportar consultas muy grandes porque colapsaban, la situación se volvía un dolor de cabeza. Y dado que no era viable una solución trivial como hacer llamadas individuales para cada elemento porque eso no es eficiente, es costoso y poco sostenible , necesitaba una forma simple…  ( 5 min )

Author: Andrei Leonov Introduction What if an AI could discover physical laws — not by being told the answer, but by evolving its own formulas? What if the result looked like pure nonsense — yet hid a physically perfect structure underneath? This is the story of a formula that is at once absurd and brilliant. Generated by symbolic regression using genetic programming (GP), the expression appeared chaotic and unreadable. But after careful analysis, it revealed a deep, interpretable pattern — one that could be used in physics, geometry, and even memory modeling in AI systems. The Raw Formula (a Monster) X′ = neg(((tanh(x) / pi) * (1 + p1))) The formula was one of many evolved by a symbolic GP system trained only to minimize MSE — no physics was built in. At first glance: complete chaos. Deep…  ( 4 min )

LeetCode 3405 | Hard | Combinatorics You are given three integers: n: length of the array m: range of values [1, m] k: number of adjacent equal pairs You must find the total number of "good arrays", where: Every element lies in the range [1, m] Exactly k indices i (where 1 ≤ i < n) satisfy arr[i - 1] == arr[i] Since the result may be large, return the count modulo 10⁹ + 7. To construct a valid array: Pick k positions (from the n - 1 possible adjacent pairs) to be equal. The first element can be any value from 1 to m. For each of the n - 1 - k remaining positions (which must differ from the previous element), there are m - 1 options. So, the total number of such arrays is: C(n - 1, k) × m × (m - 1)^(n - 1 - k) Where: C(n - 1, k) is the number of ways to choose k adjacent positions to…  ( 5 min )

What is a Hook? Hooks allow function components to have access to state and other React features. Because of this, class components are generally no longer needed. Hooks allow us to "hook" into React features such as state and lifecycle methods. Why used Hooks? Although Hooks generally replace class components, there are no plans to remove classes from React. Hook Rules** There are 3 rules for hooks: Hooks can only be called inside React function components. Note: Hooks will not work in React class components. useState in React React's useState hook lets you add state to functional components. import { useState } from 'react'; function Counter() { return ( Count: {count} An array is a list-like object used to store multiple values in a single variable. const fruits = ['apple', 'banana', 'cherry']; Arrays can hold any data type — strings, numbers, objects, or even other arrays. The Spread Operator (...) The spread operator allows you to quickly copy or merge arrays and objects. const original = [1, 2, 3]; console.log(copy); // [1, 2, 3] Adding elements: const numbers = [1, 2, 3]; console.log(moreNumbers); // [1, 2, 3, 4, 5] Merging arrays: const a = [1, 2]; console.log(combined); // [1, 2, 3, 4] Using map() to Transform Arrays The map() method lets you apply a function to every element in an array and returns a new array. const numbers = [1, 2, 3]; console.log(doubled); // [2, 4, 6] In React, map() is commonly used to render lists of components: const items = ['pen', 'notebook', 'eraser']; return ( {item} )} );  ( 3 min )

"Your database is fighting itself—and the reads are winning."

What is Blockchain? Blockchain is a decentralized, permanent digital ledger that records transactions across many computers. This setup makes it nearly impossible to change past records. Instead of relying on a central authority (like a bank), blockchain promotes transparency, security, and efficiency by sharing control among participants. Transactions are grouped into blocks, and each block links to the previous one, creating a chain. These blocks are protected using cryptography, ensuring the data inside can’t be altered once added. A blockchain runs on a peer-to-peer network. When a transaction happens: It is broadcast to many computers (called nodes). The nodes verify the transaction through consensus methods like Proof of Work (PoW) or Proof of Stake (PoS). Verified transactions are…  ( 5 min )

As a student developer who is exploring AWS technologies, I recently came across Amazon Q and its current event. The event encouraged participants to build a game, and that instantly hit a nostalgic chord in me. A few years ago, I've created a simple game in Unity without knowing how to code. Now, equipped with two years of coding experience and the help of Amazon Q, I managed to recreate that idea as a full parody arcade game using pygame-ce in just one day! Although AI tools are not new to me and to everybody, it still amazes me how much faster development becomes with the use of it. So in this short post, I’ll be sharing a quick look at how Amazon Q helped me bring this fun small project to life. The game is called the "The Last Bluebook".

This is the third release of Pulumi Gestalt, a universal runtime for Pulumi. Pulumi schemas have traditionally been stored in YAML files, but the complexity of their content often leads to a lot of boilerplate when mapping into domain objects. In Pulumi Gestalt 0.0.3, both the Rust and C FFI targets (Wasm coming later) now support obtaining schemas as native Rust structs or serialized Protobuf messages for C. The Protobuf schema is designed to be straightforward—no additional mapping logic required. Check documentation for more info: https://pulumi-gestalt.readthedocs.io/v0.0.3/integrations/overview/#get-schema https://pulumi-gestalt.readthedocs.io/v0.0.3/integrations/schema/ Give Pulumi Gestalt 0.0.3 a try and let me know what you think!  ( 3 min )

TL;DR: When building a real-time video rendering and encoding pipeline in C++, I hit a surprising bottleneck: memory allocation. Despite using high-performance libraries like OpenGL and FFmpeg, the cost of safely copying ~5MB per frame killed my frame budget. The fix? Using raw pointers with a manually managed double buffer. It’s not idiomatic C++, but in this case, “unsafe” code—done carefully—was the only way to hit performance targets. As a person who worked in managed runtimes like NodeJs and the Golang runtime, thinking about memory management always felt like premature optimisations because the runtime, or the underlying libraries generally handled it really well. However, in C++ it is the name of the game. The language offers multiple ways to manage memory and resource lifecycles …  ( 5 min )

A groundbreaking study from Japan has uncovered direct brainwave patterns linked to our experience of happiness. Using advanced magnetoencephalography, or MEG, scientists identified a clear neural signature that differentiates happier minds from the rest. Researchers recorded brain activity from volunteers at rest and compared those signals against their self reported happiness levels using standard psychological questionnaires. They discovered that higher subjective happiness was associated with lower fluctuations in gamma band electrical activity in a key brain region called the right precuneus. This area is known to be involved in self awareness and mind wandering. To reach this conclusion, the team employed a 400 channel MEG helmet to capture high resolution brain data.

Today hit us with another round of Apple rejection. 😅 This time it wasn’t technical — at least not completely. Apple flagged us for a broken link and asked for further clarification on what our app actually does. It’s frustrating, sure. After working so hard to build something safe, educational, and magical for kids — it’s a gut punch to feel like we’re stuck behind bureaucracy. But we're not giving up. We took today to carefully review the rejection notes, update our metadata, fix the link issue, and prepare a new submission. The worry now is time: with only 13 days left, will we have a working version live in the store before the hackathon ends? It’s a risk, but we’re still in this. We believe in Story Hero too much to let some red tape stop us. The Apple review process is famously opaque. But we’re committed to learning it, navigating it, and getting this app live — even if it takes a few more tries. One way or another, we’ll launch.

子から親へ: emitでイベントを通知する 子コンポーネントから親コンポーネントへデータを送り返したり、何らかの操作を親に伝えたりするには、 イベントを発行 (emit) します。子コンポーネントから「こういうことがあったよ !」と親に知らせるイメージです。 +---------------------+ | 親 コンポーネント | | (ParentComponent) | +---------------------+ ^ | データ渡し (emit) | +---------------------+ | 子 コンポーネント | | (ChildComponent) | +---------------------+ 子コンポーネントでの記述: defineEmits() で発行するイベントを定義し、emit 関数でイベントを発行します。 親へデータを送る import { defineEmits } from 'vue' // 'child-data-sent' という名前のイベントを定義 const emit = defineEmits(['child-data-sent']) const sendDataToParent = () => { // 'child-data-sent' イベントを発行し、データを一緒に渡す emit('child-data-sent', '子コンポーネントからのメッセージです !') } defineEmits() は 構文でイベントを定義するためのマクロです。 (defineProps() と同様) emit 関数の第 1 引数にイベント名、第 2 引数以降に渡したいデータを指定します。 親コンポーネントでの記述: 子コンポーネントのタグ上で、@ (v-on の略記) を使ってイベントを監視し、イベント発生時に実行するメソッドを定義します。 子から受け取ったメッセージ: {{ receivedMessage }} { receivedMessage.value = data console.log('親コンポーネントでイベントを受け取りました:', data) } @child-data-sent のように、イベント名を @ の後に記述します。 イベントハンドラーのメソッドの引数には、子から送られたデータが自動的に渡されます。 props と emit は、コンポーネント指向開発における基本的なデータ連携のパターンです。これらを使いこなすことで、整理されたコンポーネント構造を保ちながら、複雑な UI を実現できます。  ( 3 min )

Em arquiteturas modernas, especialmente com microserviços e comunicação entre sistemas distribuídos, o uso de APIs REST pode não ser o mais eficiente.

Open your favorite banking app. Tap to send money. If it hesitates even a second, what do you do? That brief pause – barely noticeable in most apps – can be a deal-breaker in financial services. Trust is measured in milliseconds. According to a study by Akamai, a mere 100-millisecond delay in website load time can hurt conversion rates by 7%. For mobile banking, where stakes are higher and users are less forgiving, the impact compounds. FinTech isn’t just software – it’s infrastructure. And users expect infrastructure to be fast, always available, and invisible when working correctly. When it fails, it’s not just annoying – it’s a breach of trust. Performance QA testing for mobile apps in banking and payments is no longer a nice-to-have. It’s a safeguard for customer retention, brand credi…  ( 7 min )

"A confusão começa quando diferentes áreas de negócio compartilham um mesmo modelo de dados." — Eric Evans Com o crescimento de aplicações, principalmente em arquiteturas de microserviços, cresce também a complexidade de lidar com múltiplos domínios de negócio. É aí que entra o DDD (Domain-Driven Design) e seu conceito-chave: o Bounded Context. Neste artigo, vamos explorar como aplicar DDD com Bounded Contexts na prática, utilizando .NET 8, organização de pastas e exemplos reais. Um Bounded Context é uma fronteira explícita dentro de um domínio, onde um modelo específico é definido e aplicado de forma consistente. Na prática, isso significa separar funcionalidades como Financeiro, Cadastro, Logística, etc., em contextos independentes — cada um com seu vocabulário, regras de negócio e estru…  ( 5 min )

The most impressive addition is automatic comment generation. An on-device model analyzes your code and writes contextual comments that translators actually need. We've all been there. You write a string like this: Text("Delete", comment: "Delete button shown in an alert asking for confirmation to delete the collection.") But more often, we rush and write this: Text("Delete") // TODO: Add comment for translators The TODO never gets done. Translators see "Delete" with zero context. Is it a verb? A noun? What's being deleted? Right-click any string in your String Catalog and select "Generate Comment." The results are surprisingly sophisticated: // Original string with no context Button("Cancel") { } // AI-generated comment: // "The text label on a button to cancel the deletion of a collec…  ( 6 min )

Amazon/AWS people speak a lot on how they're customer obsessed, and have a bias for action. And sometimes it sounds like talking points. But, lately, I got to experience first-hand how AWS listens (and reacts) to community feedback! The story is actually quite short, given how fast my feedback was taken into account. On May 19th, I created an IAM user for a subcontractor, let's call him John, who was supposed to work on a data lake project, so I named that user john and put him in the /datalake/ path. I set a temporary Console password and assigned the IAMUserChangePassword policy to that user. But later that day, John gets in touch; quite pissed: "I can't reset the password for the account you gave me, and as a result AWS won't let me sign in". At first, I couldn't understand: I had d…  ( 4 min )

1. Introduction Solidity is one of the most widely used programming languages in the Web3 space, especially on Ethereum and Ethereum Virtual Machine (EVM) compatible chains. As smart contract development has evolved, developers have encountered several challenges, particularly when trying to build complex, upgradeable, and gas-efficient contracts. One major limitation is Solidity's 24KB maximum contract size, which restricts the amount of logic that can be deployed in a single contract. This has led developers to explore different upgradeability patterns and modular architectures. To address these limitations, Nick Mudge proposed the Diamond Standard (EIP-2535). This standard provides a framework for building modular, upgradeable smart contracts in a structured way. By organizing contrac…  ( 6 min )

One thing I learned about: Alternatives to using blockchain nodes Blockchains do not always need to use full nodes for every task in the network. They can use alternatives suited to their goals, circumstances, and constraints. Examples: Light clients: performs trust-minimized verification by requesting proofs from full nodes. Data availability layers: store and serve block data apart from execution nodes. Layer2 and sidechains: process data off-chain and rely on proofs or state roots. Blockchain indexers: store data and allow queries nodes do not support. Remote or federated APIs: third-party on-chain data providers 🔽🛠️Resources🔽 What is Data Availability in Blockchain?

“Rust is the skill. Polkadot is the playground. And you? You’re the architect.” For the past few months, I’ve been heads-down writing about Go — breaking down structs, interfaces, and everything in between. It was the language that helped me fall in love with code and gave me a strong foundation in backend development. But something kept calling me: blockchain. As I explored the space, I didn’t want to just write smart contracts or build on top of existing blockchains. I wanted to understand the core — the real infrastructure that powers the decentralized world. That’s when I stumbled into the Polkadot ecosystem — a vision of Web3 that goes beyond just blockchains. It’s about connecting them all, and empowering developers to build their own chains using powerful tools. And guess what? The …  ( 5 min )

Every developer using an AI coding assistant has felt the jarring whiplash of its brilliance and its absurdity. One moment, it scaffolds a complex class structure perfectly; the next, it confidently uses a deprecated method or hallucinates an API that never existed. This problem becomes critical when building complex, stateful systems like those powered by LangGraph. An unguided AI can quickly lead you down a rabbit hole of debugging non-existent features. But what if, instead of just prompting and hoping for the best, we could engineer the environment our AI assistant operates in? What if we could force it to be a reliable, expert partner? This article introduces a framework to do just that. It's a system for grounding AI assistants, making them highly effective tools for building product…  ( 6 min )

Picture this: You've containerized your full-stack application, everything works beautifully in development, but when you deploy to production, services can't find each other, performance tanks, or worse - security boundaries disappear. Sound familiar? Docker networking is often treated as a "set it and forget it" configuration, but understanding the three core networking modes - Bridge, Host, and Overlay - can be the difference between a scalable, maintainable application and a debugging nightmare. In this guide, we'll explore each networking mode through the lens of a practical e-commerce application, examining when to use each approach and the trade-offs involved.

So you've decided to build a complex, multi-step AI agent. You fire up your AI coding assistant, describe your goal, and ask it to scaffold a LangGraph application. What you get back looks plausible, but then you spot it: a call to a deprecated function, an import from a library that's changed, or a hallucinated parameter that doesn't exist. This is the chaotic reality of modern AI-driven development. Our tools are incredibly powerful but operate with outdated knowledge and no sense of best practices. It feels like working with a brilliant but forgetful intern. What if we could change that? What if we could build a system that forces our AI assistant to be a reliable, expert partner?

Ever wondered if you should use Transfer Learning or go all-in with Fine-Tuning when adapting a pretrained model? 🤔 If you’re working with something like BERT or LLaMA 2, choosing the right approach can save you serious time and compute costs. Here’s the quick breakdown: Transfer Learning is great when you just need to tweak the model a bit freeze most layers, retrain the final ones, and you’re good to go. Fast and efficient. Fine-Tuning, on the other hand, updates the whole model. It’s heavier, but sometimes necessary when your use case is highly domain-specific (think legal, medical, or financial AI). We made a short video explainer that walks through both options and when to use each. If you’re building anything from sentiment classifiers to custom chatbots, it might help clarify the path forward. Let us know if you're exploring this in your own AI project! 👀  ( 3 min )

Hot take: We're using the wrong tool for the job. Your TypeScript types are giving you a false sense of security where it matters most. Let's be honest. We adopted TypeScript for safety. And for the code you write and control, it gets the job done. But where do the most dangerous bugs originate? From the outside world: API responses, user input, webhook payloads. Then here comes TypeScript to do absolutely nothing. That's right. TypeScript, a compile-time tool, is completely silent when your app receives malformed JSON at runtime. Your beautiful type User = { id: number; } offers zero resistance when an API mistakenly sends { "id": "user-123" }. The code compiles, your app runs, and then it crashes. This fundamental gap forces us into a clumsy, defensive workflow that I call the "Two-Sou…  ( 5 min )

I started my DSA journey pretty recently. It was like a passport to product based companies - solve 'n' number of problems and get 'n' number of offers. 1. Think patterns not topics Most questions can be solved using a single pattern. You don't have to solve 3000 problems to master DSA but master the patterns to which 3000 problems can be solved. For example in arrays and strings most questions were easily approachable using binary search, two pointers and sliding window. 2. You will look at solutions repeatedly. Don't worry happens to everyone 3. It improves project logic Should I use set for faster lookups? Can I reduce the number of API calls by memoizing it? DSA taught me that even product-based features have their space and time complexities. 4. DSA humbles you Conclusion I'm not saying learning DSA will guarantee you a job at a top product based company. Just how learning ABCs is a fundamental unit before adapting to fluent english. DSA is a fundamental unit before adapting to project devlopment. Mastering DSA is extremely beneficial, provided you do it the right way. Don't just solve problems but also try implementing that knowledge into your existing projects and see how can it be further optimized. Your not just preparing for an interviews. You're training to be a problem solver- which is a superpower in any domain.  ( 5 min )

Date of writing: 16-06-2025 Given a 0-indexed integer array nums of size n, find the maximum difference between nums[i] and nums[j] (i.e., nums[j] - nums[i]), such that 0 <= i < j < n and nums[i] < nums[j]. Return the maximum difference. If no such i and j exists, return -1. This problem, in initial thought, seems pretty simple. We simply need to find the biggest difference between 2 numbers, if the latter of those 2 numbers is bigger then first number. I believe we can do this in a O(n) solution, keeping track of some numbers whilst we go through the list! The first pseudo code I can think of is as follows: const maxDifference = -1; const smallestIndex = 0; for (int i = 0; i < numbers.length; i++){ if i is equal to numbers.length - 1 : // We are at the end of the list, so…  ( 7 min )

I’ve been building with React for years, and every time the app grows, so does the complexity around managing state. Yes, I’ve used Redux Toolkit. Yes, Zustand is sleek.

That question sparked a journey — of breaking down there Architecture, understanding what they solve, and what they still miss. As frontend devs , especially in React, we’ve all had this moment. We reach for state management, and suddenly, a simple feature blows up into a complex web of files and concepts. Redux Toolkit (RTK) today is certainly better than raw Redux.

Introduction This project aims to automate the deployment of Java applications to an Apache Tomcat server using Jenkins. Instead of manually building and copying .war files, we use a CI/CD pipeline where Jenkins pulls code from a Git repository, builds it using Maven, and deploys it to Tomcat automatically. This streamlines the development process, reduces human error, and enables faster, more reliable application delivery, following modern DevOps practices. Manual deployment of Java applications is time-consuming and error-prone. This project solves that by introducing automation using Jenkins, which ensures that every time code is updated, it is built, tested, and deployed automatically to a Tomcat server. It saves developer time, reduces bugs, and supports faster and more reliable so…  ( 5 min )

A major leap forward in battery technology has just been achieved. Scientists at the University of Manchester and the University of Technology Sydney have developed a novel two dimensional superlattice material that could revolutionize zinc ion batteries. The new material significantly improves performance, stability, and longevity, addressing key limitations that have long held this promising battery type back. Zinc ion batteries are already considered safer and more environmentally friendly than traditional lithium ion batteries. Zinc is abundant, non toxic, and easier to recycle. However, until now, these batteries have suffered from short lifespans and limited charge discharge cycles, largely due to instability in the electrode materials. That is where the new superlattice design comes…  ( 4 min )

By using the media attribute, you can apply different styles to different devices, screen sizes, or conditions. Its value is a media query, which is default to all if the media attribute is missing. The media attribute is allowed with an if its parent element is an element but is not allowed if its parent element is an or element. source tag The tag is used to specify multiple media resources for media elements, such as , , and . The tag allows you to specify alternative video/audio/image files which the browser may choose from, based on browser support or viewport width. The browser will choose the first it supports.

When you're building geospatial applications, it's surprisingly easy for users to accidentally create duplicate or very close records. Imagine trying to add a location (like a traffic signal or utility pole) at a GPS point that’s just 30 feet away from an existing one. Should the system allow that? Should the user be warned? In this post, I’ll show how I implemented a proximity detection system using the Haversine formula in Java to solve this problem cleanly and effectively. My goal was to prevent duplicate entries by: Calculating the distance between the new location and existing ones Alerting the user if any location was within X feet (say, 100 ft) Letting them decide whether to continue So instead of relying on exact latitude/longitude matches, we used distance-based detection. The Ear…  ( 4 min )

In this article, we explore how to build a simple but powerful Retrieval-Augmented Generation (RAG) system using NeuronAI and Ollama. Whether you're building an AI assistant that can search your documentation or a bot that provides grounded answers based on custom content, this guide will walk you through the key concepts and implementation steps. RAG is an AI technique that combines the strengths of information retrieval with natural language generation. Instead of relying purely on what a model has memorized during training, a RAG system actively fetches relevant data from an external source and uses it to craft accurate, contextually relevant responses. Accuracy: ground responses in actual documents rather than model guesses. Custom knowledge: use your own content as the source of truth…  ( 8 min )

Instead of building a complex API surface for your AI agent, make it interact with your app like a human user would. Use the Accessibility Object Model (AOM) to give your agent “eyes” to see the UI and “hands” to interact with it. This approach is simpler, more maintainable, and has the bonus of making your app more accessible for screen readers. Read on  ( 3 min )

🤓 Introduction I have a HP laptop I bought in year 2016. It had the top specs a mid-range gaming laptop can have at that point. Many users like me often attribute this as an hardware failure, but the real issue is (most of the time) the operating system, which in my case was Windows. In addition to that, Microsoft has randomly dropped the bomb, that Windows 10 will be out of support starting Oct 25, and many of these old hardware cannot run official Windows 11 image. This is the perfect opportunity to explore some Linux based distros. These reasons are coming from my personal experience, let's see why I like Kubuntu.

When working with JavaScript and React, there are a few core concepts that you’ll use again and again: arrays, the spread operator (...), the map() function, and React's useState hook. In this blog, we’ll break each one down with simple examples so you can understand how and when to use them effectively. An array is a list-like object used to store multiple values in a single variable. const fruits = ['apple', 'banana', 'cherry']; console.log(fruits[0]); // Output: apple Arrays can hold any data type — strings, numbers, objects, or even other arrays. The spread operator allows you to quickly copy or merge arrays and objects. const original = [1, 2, 3]; const copy = [...original]; console.log(copy); // [1, 2, 3] Adding elements: const numbers = [1, 2, 3]; const moreNumbers = [...number…  ( 4 min )

I built and sold my first Tailwind portfolio template — here’s what I learned Hey Devs! 👋 I recently challenged myself to build a complete developer portfolio template using just HTML, Tailwind CSS, and vanilla JavaScript. Originally, I planned it for my personal site, but I decided to polish it and publish it as a product. That small decision turned into one of the most exciting moments in my dev journey so far! It’s a simple but modern portfolio template that includes: 🌙 Dark / Light Mode toggle 📱 Responsive layout (desktop & mobile) ⚡ Scroll animations 📁 Project section with tech tags 📩 Contact form UI 📄 Resume download button 🧠 Vanilla JS + Tailwind CSS 🧼 Clean structure (HTML, CSS, JS separated) Honestly? I wanted to test if a beginner-friendly template with good visuals and real features could be useful for: Developers applying for jobs Students graduating from bootcamps Freelancers needing a fast, clean portfolio And... turns out it was. Even without followers, some people found the template through social platforms and started buying! You don’t need a giant audience to start. Simple, real-world tools (like Tailwind + HTML) are still in demand. Gumroad, Itch.io, and Payhip are great for selling digital stuff — no code needed. If you create something useful, people will find it. 🔗 Live Demo: [Link in my Dev.to profile] 🛍️ Gumroad page: [Link in my profile too] I didn’t put the links directly here just in case the post gets filtered, but they’re visible in my Dev.to bio section. 😄 If you’ve ever hesitated to share or sell what you’ve built — just try it.
